Description

SYSTEM AND METHOD FOR DRILLING PLAN GENERATION
TECHNICAL FIELD
The present invention relates to a method for drilling plan generation. The invention also relates to a computer program product comprising program code for a computer for implementing a method according to the invention. The invention also relates to a system and a drilling rig being equipped with the system.
BACKGROUND Electronic drilling plans are today used in for example the mining industry. These drilling plans are used as instructions and means for per segment drilling a number of holes in the body which is to be blasted and emptied on material. Said drilling plans comprise information about for example where starting points and end points are positioned and which diameter each said drilling hole shall present. Hereby such start points for drilling holes and direction, length and diameter of each drilling hole are specified. Hereby is also presented the distribution of said drilling holes in said body. An operator of a drilling rig may hereby use a sequence of different predetermined drilling plans so as to subsequently drill a number of predefined holes for blasting, whereby a desired tunnel or drift may be created in for example a mountain or a mine.
Said electronic drilling plans are today developed in advance at for example a planning centre, whereby said drilling plans are stored on a portable memory and brought by the operator to the drilling rig which is to be used for drilling. Thereafter said electronic drilling plans are loaded into a computer arranged at the drilling rig for use during operation of the drilling rig.
A drilling plan may be presented in two or three dimensions on a presentation screen of said computer. The drilling plan may comprise a number of different sectors which may be presented as a surface in two dimensions or as a volume in three dimensions. One such sector is denoted wedge. A number of adjacent sectors are also specified. Other sectors in the drilling plan are denoted stopes. A common set of stopes of a drilling plan defines a left and right stope, which are positioned to the left and right of said wedge, respectively. Further, a sector positioned adjacently above said left stope, wedge and right stope usually is denoted upper stope. In a similar way a sector beneath said left stope, wedge and right stope is denoted lower stope. Said four sectors may be surrounded by a so called inner contour and an outer contour. Said outer contour is defining an outermost boundary for starting points of drilling holes. A part of said outer contour may be denoted bottom row, defining a lowest boundary, i. e. corresponding to the ground.
After drilling holes have been drilled in accordance with a provided drilling plan these are filled with explosives, whereby a suitable blast in performed. Typically sections are blasted in a sequence regarding said sectors and contours, where said wedge is blasted first, thereafter side stopes, upper wedge and lower wedge are blasted. Said inner and outer contour are blasted in a suitable way.
These drilling plans are today static and do not allow for an operator to adapt the same to prevailing circumstances, paying regard to for example characteristics, such as cracks of the material in the body of the section to be drilled and blasted. Hereby it may be necessary to develop a new drilling plan at said planning centre, which leads to undesired delays of the drilling procedure, which delays are associated with high costs.
SUMMARY OF THE INVENTION
There is thus a need to, in a reliable and user-friendly way, adapt existing drilling plans for a drilling rig. There is hereby a need to, in a time-effective and user-friendly way, allow adaption of existing drilling plans for a drilling rig on site of said drilling rig in connection with the operation thereof.
An object of the present invention is to provide a new and advantageous method for drilling plan generation.
Another object of the invention is to provide a new and advantageous system for drilling plan generation and a new and advantageous computer program for drilling plan generation.
Another object of the invention is to provide an alternative method for drilling plan generation, an alternative system for drilling plan generation and an alternative computer program for drilling plan generation of a drilling rig. Yet another object on the invention is to provide a method, a system and a computer program for flexible drilling plan generation wherein a new drilling plan may be generated, which new drilling plan hereby may be adapted to existing circumstances during operation of a drilling rig.
Another object of the invention is to provide a method, a system and a computer program for drilling plan generation so as to achieve a more time-effective, and hereby cost-effective, operation of a drilling rig.
Some of said objects are achieved with a method for drilling plan generation according to claim 1. Other objects are achieved by a system for drilling plan generation according claim 6. Advantageous embodiments are specified in the depended claims.
According to an aspect of the present invention there is provided a method for drilling plan generation where a drilling plan is specifying a number of drilling holes having a starting point and an end point, which drilling holes are distributed within sectors specified in the drilling plan, which sectors comprise a first sector specifying a so called wedge and at least one second sector adjacent to said first sector, comprising the steps of:
- on the basis of an existing drilling plan, automatically generating a new drilling plan where said first sector is positioned in a new position compared to said existing drilling plan;
- determining rules specifying drilling holes of said existing drilling plan; and
- applying the thus determined rules in said new drilling plan and adapting dimensions and position of said at least one second sector to said new position of said first sector in said new drilling plan.
Said existing drilling plan and said new drilling plan are electronic drilling plans. Said existing drilling plan is an in advanced specified drilling plan. Said new drilling plan may be generated on site for drilling of a drilling rig. By allowing generation of said new drilling plan on site for drilling an operator of the drilling rig may adapt positioning of said first sector to prevailing circumstances. Hereby position of a wedge of said existing drilling plan may be changed, wherein an adaptation of said at least one second sector may be performed dynamically in dependence thereof.
Advantageously, an operator may hereby, by means of for example a presentation screen where said existing drilling plan is presented, change position, and potentially dimensions, of said first sector in a desired way, whereby a new drilling plan automatically may be generated where adaptations are performed in relation to said changed position. It may be desired to change position of said first sector of the existing drilling plan considering cracks of the body where drills are to be positioned to start a hole. It may also be desired to change position of said first sector of the existing drilling plan when the surface of the body where drills are to be positioned to start a hole is presenting a non- favourable surface structure which make starting a hole and initial drilling more difficult. It may be desired to change position of said first sector of the existing drilling plan when an operator wishes to alternate the position of the wedge horizontally for successive segments of the body, corresponding to successive drilling plans. Hereby, a more advantageous position of said wedge in successive drilling plans may be achieved in a time-effective and user-friendly manner.
Hereby, an operator may for various reasons decide to change position of said first sector of the existing drilling plan so as to adapt the same to prevailing circumstances. Hereby, a flexible method for generation of drilling plans according to the invention is provided.
Hereby, a suitable adaptation of positioning and orientating of drilling holes in said new drilling plan may be determined in a time-effective and user-friendly manner. According to an embodiment drilling holes of different sectors in the original drilling plan may be specified according to unique rules for each sector. By automatically determining which rules are valid for said at least one second sector these rules may be applied and implemented on a corresponding sector in the new drilling plan. Said rules may for example relate to desired row distances (burden) and hole distances as well as which dimension drilling holes within said sector shall have. It should be noted that rows of holes do not necessarily need to be horizontal and vertical even if this is often the case. Determination of said rules may be initiated manually by an operator of a drilling rig where said new drilling plan is generated. Hereby predetermined rules may be used for adaptation of a drilling plan to prevailing circumstances on site for drilling. The method may comprise the steps of:
- specifying said existing drilling plan in such a way that it comprises said first sector and four more sectors, comprising a sector on each side of said first sector and an upper sector, positioned above said first sector and the sectors on each side of said first sector, and a lower sector positioned under said first sector and the sectors on each side of said first sector; and
- in said existing drilling plan, specifying said sectors within the frame of an outer contour;
- specifying said new drilling plan in a corresponding way.
Hereby an existing drilling plan may be used as basis for specifying a new drilling plan, which is both time-effective and user-friendly.
The method may comprise the steps of:
- specifying said new drilling plan in such a way that said first sector is moved horizontally to the right or to the left; - adapting dimensions and positions of sectors on each side of the new position of said first sector.
Hereby a user-friendly, flexible and automatic generation of the new drilling plan is achieved. If said first sector is moved horizontally to the right or to the left only the dimensions and positions of the sectors on each side of the new position of said first sector are affected. This means that dimensions and position of a provided upper stope and the dimensions and position of a lower stope do not need to be affected by such a movement. Hereby a method for generating a new drilling plan which is not associated with a heavy computational burden is achieved.
The method may comprise the steps of:
- specifying said new drilling plan in such a way that said first sector is moved vertically in a direction upwards or downwards;
- adapting dimensions of and positions of all sectors surrounding said first sector and its new position. Hereby a user-friendly, flexible and automatic generation of the new drilling plan is achieved. If said first sector is moved vertically upwards or downwards the dimensions and positions of sectors adjacent to the new position of said first sector may be affected. This means that the dimensions and positions of the provided upper and lower stopes as well as dimensions and positions of said side stopes may be affected by such a move. Hereby a flexible and user-friendly method according to an aspect of the present invention is provided.
It should be noted that the first sector of the existing drilling plan may be moved both horizontally and vertically, i. e. diagonally. During a diagonal movement dimensions and positions of a provided upper and lower stope and dimensions and positions of said side stopes may be affected. Hereby a flexible and user-friendly method according to an aspect of the present invention is provided.
The method may comprise the steps of:
- on the basis of said existing drilling plan, generating said new drilling plan wherein said first sector has new dimensions compared to said existing drilling plan; and - adapting dimensions and position of said at least one second sector to the new dimensions of said first sector in said new drilling plan.
According to an embodiment dimensions of said first sector may be changed, i.e. the size of the first sector represented in two dimensions may be made larger or smaller. Hereby, the rules which have been determined for drilling holes of the first sector in the existing drilling plan may be used for generating a new set of drilling holes for the first sector in the new drilling plan. Hereby the number of drilling holes associated with the first sector which has been changed in size in the new drilling plan may be larger or smaller. A flexible method according to an embodiment of the invention is hereby achieved. Sectors defining adjacent stopes in the new drilling plan may hereby be adapted dynamically to the new dimensions and position of the first sector. According to an embodiment a wedge being defined of a first sector in the existing drilling plan may be replaced by another wedge, which hereby may have a different size than the wedge in the existing drilling plan. This new wedge, and hereto associated rules for drilling holes, may hereby be introduced in new drilling plan, whereby adaptation of positions and dimensions of the other sectors of the new drilling plan may be performed automatically. This new wedge may have predetermined dimensions and a predetermined drilling hole distribution, where the new wedge thus may be based on predetermined rules. Alternatively, rules for a new wedge may be determined and applied on site at the drilling rig.

Figure 3a schematically illustrates an example of an electronic drilling plan PBP. Said drilling plan PBP is hereby an existing drilling plan. Said existing drilling plan PBP is generated in advance. Typically said drilling plan PBP may be generated at a planning centre which is located remotely from the site of drilling with said drilling rig 100. Said drilling plan PBP may be provided to said first control unit 200 in any suitable way, for example by means of a portable memory or via a link communication, such as a wireless link or a physical wire.
A drilling plan is a model presenting how a number of holes are to be drilled in a segment of a tunnel. A segment may for example be 5 meters long, and hereby corresponds to a length of a body which is desired to first be drilled, then blasted and thereafter emptied of material.
The illustrated drilling plan PBP is hereby illustrated in a view in a main direction of a thought tunnel. The drilling plan PBP is presented in a vertical view (comprising a local 2D projection). In a drilling plan starting points of a number of drilling holes and how each such drilling hole is to be directed are presented. A starting point is presented as a circle in a drilling plan. Further, an end point is illustrated by a projection of a drilling hole running from said starting point. Such a projection of a drilling hole is illustrated as a line projecting from said circle regarding entry position of a drilling hole. Hereby a direction and end point of a certain drilling hole may be read out from said drilling plan. In a case where a drilling hole is running orthogonally to said vertical plan, i. e. straight in to the body, said projection is not presented, hereby only the starting point (the circle) is presented. The existing drilling plan PBP is presenting a first sector W, a so called wedge. Said first sector W presents a number of drilling holes to be drilled. In this case said first sector comprises five drilling holes. The respective projections of the drilling holes are showing that all drilling holes of the first sector are directed slightly obliquely upwards at a certain angle.
Herein is disclosed that a drilling plan, existing or generated, is presenting at least one second sector. Herein four such sectors are presented, according to below.
The drilling plan PBP comprises a left stope LS. Said left stope LS is presenting four drilling holes, where two are to be drilled obliquely upwards and two are to be drilled obliquely upwards to the left. The drilling plan comprises a right stope RS. Said right stope RS is presenting four drilling holes, where two are to be drilled obliquely upwards and two are to be drilled obliquely upwards to the right.
According to this example embodiment said left stope LS and said right stope RS have substantially the same height as said first sector W. Alternatively said left stope LS and said right stope RS may have mutually different shapes, which also are different from said first sector W.
The drilling plan comprises an upper stope US. Said upper stope US comprises a number of drilling holes. A drilling plan comprises a lower stope BS. Said lower stope BS comprises a number of drilling holes.
Hereby said first sector W is adjacent the left stope LS and the right stope RS as presented in Figure 3a. Said upper stope US is defined by a sector which is positioned above said first sector W, said left stope LS and said right stope RS. Said lower stope BS is positioned under said first sector W, said left stope LS and said right stope RS.
Further is presented an outer first contour IC in said drilling plan PBP. At said first outer contour IC a number of drilling holes comprising hole starting points and said respective drilling hole projection are defined. Inside said first outer first contour IC an inner second contour 2C is presented. At said inner second contour 2C a number of hole start points and said respective drilling hole projection are defined. A part of said second contour 2C is illustrated with a broken line. The part of said outer first contour 1C, which is running horizontally under said lower stope BS may be denoted bottom row.
The illustrated existing drilling plan is according to an aspect of the invention subject for a change meaning that an operator who is using drilling plans for operating said drilling rig 100 wants to move said first sector W to a more suitable position in the drilling plan. The operator may also change dimensions of said first sector W and hereby achieve a new drilling plan, according to an aspect of the present invention. Alternatively the operator may exchange said first sector W of the existing drilling plan and hereby achieve a new drilling plan, according to an aspect of the present invention. According to this example a so called wedge of the original drilling plan is exchanged with a new, different wedge in the new drilling plan.
Within each said sector and at each of said contour of the original drilling plan a distribution, positioning, dimension and orientation of a number of drilling holes are specified according to unique rules for each such sector or contour. Such different rules may be predetermined.
Hereby drilling holes of said first sector are specified according to a certain set of rules WR. Hereby drilling holes of said left stope are specified according to a set of rules LSR. Hereby drilling holes of said right stope are specified according to a set of rules RSR. Hereby drilling holes of said upper stope are specified according to a set of rules USR. Hereby drilling holes of said lower stope are specified according to a set of rules BSR. Hereby drilling holes of said first outer contour 1C are specified according to a set of rules ICR. Hereby drilling holes of said inner contour 2C are specified according to a set of rules 2CR.
With reference to the Figures 3b-3d below it is described how new generated drilling plans may look like after an operator of said drilling rig 100 has moved the first sector.
Figure 3b is schematically illustrating a changed, new, drilling plan NBP, according to an aspect of the invention. Hereby said first sector W has been moved in a horizontal direction to the right in the original drilling plan PBP. This movement may be performed by the operator at the drilling rig 100 by means of said presentation means 240. Hereby it is determined which rules are associated with said left stope LS and with rules are associated with said right stope RS, namely LSR and RSR. These rules may be the same rules. Hereby a new left stope LS and a new right stope RS are generated on the basis of said new position of said first sector W where drilling holes for said new left stope LS and said new right stope RS are generated on the basis of said respective determined rules.
In Figures 3b-3d it is illustrated a part of a contour B1C which will define the first outer contour in a subsequent segment of the body, which contour B1C may define an outer contour 1C for said subsequent segment of the body. This is also illustrated in Figure 3e in greater detail.
Figure 3c schematically illustrates a changed, new, drilling plan NBP, according to an aspect of the invention. Hereby said first sector W has been moved in a vertical direction upwards in the original drilling plan PBP. This movement may be performed by the operator at the drilling rig 100 by means of said presentation means 240. Hereby it is determined which rules are associated with said left stope LS and which rules are associated with said right stope RS, namely LSR and RSR. It is further determined which rules are associated with said upper stope US and which rules are associated with said lower stope BS, namely USR and BSR.
Hereby a new left stope LS and a new right stope RS are generated on the basis of said new position of said first sector W where drilling holes of said new left stope LS and said new right stope RS are generated on the basis of said respective determined rules. Hereby it is generated a new upper stope US and a new lower stope BS on the basis of said new position of said first sector W where drilling holes for said new upper stope US and said new lower stope BS are generated on the basis of said respective determined rules.
Figure 3d schematically illustrates a changed, new, drilling plan NBP, according to an aspect of the invention. Hereby said first sector W has been moved in a diagonal direction obliquely upwards to the right in the original drilling plan PBP. Hereby corresponding relevant steps which have been described with reference to Figure 3b and Figure 3c are performed.
Figure 3e schematically illustrates a side view of a drilling plan NBP. Hereby drilling holes HlCl, H2C1 and H3C1 which have been illustrated with reference to Figure 3b are illustrated. The distance between 1C defining a start plane for drilling and B1C defining an end plane for drilling may be an arbitrarily suitable distance, for example 5 meters. It is thus the length of the segment of the body to be drilled and blasted. Hereby is illustrated that said drilling hole HlCl has a direction to some extent inclined upwards. Hereby is illustrated that said drilling hole H2C1 has a direction to some extent inclined downwards. Hereby it is illustrated that said drilling hole H3C1 has a direction running orthogonally to said start plan (which in this case is vertical) in to the body.
It should be noted that said start plane and said end plane may present an orientation which is not vertically orientated. Hereby, an electronic drilling plan may relate to a segment where said start plane and said end plan are not vertically oriented.
