Description
Technical field
The invention belongs to engineering explosion field, in particular to a kind of adaptive method for arranging of blasthole.
Background technique
Bench blasting is mainly used for the earthwork evacuation construction work that stripping and railway, highway cutting and water conservancy, water power are adopted in mine
Journey is a boundless blasting technique of application prospect.
The quality of bench blasting effect directly affects the operating efficiency of the subsequent handlings such as scraper, transport.Therefore, how to improve
The quality of bench blasting is always the project that numerous technical staff endeavour research.The quality of bench blasting generally has claimed below：
（1）Rock fragmentation after explosion meets the requirements；（2）Stair working face after explosion wants regular, does not allow foundation, umbrella rock etc. occur
Phenomenon.
Currently, some glory-holes use Big Diameter Hole Drills both at home and abroad, great Qu, multiple rows of elementary errors deep hole blasting are realized, it is right
Hole pattern parameters, charge constitution, filling method, firing order, millisecond crushing blasting are all compared and are in depth studied, explosion skill
The improvement of art substantially increases strip mining transformation comprehensive production efficiency.In addition, with the update of drilling machine equipment, commercial explosive and
The continuous improvement of detonator quality, new varieties explosive and high-precision, multi-segment millisecond electric detonator, on-electric detonator and digital electric detonator
Use, so that deep hole blasting technology has been obtained further development.
The progress of air bench blasting technology in recent years can generally be summarized as the following：（1）Design, drill,
The processes such as powder charge use monitoring technology, and mechanization, automation is done step-by-step；（2）Sequence blasting is widely used and broken charges are micro-
Poor blasting technique；（3）According to the difference of lithology, reasonable blasting parameter and suitable explosive kind are selected；（4）Using calculating
Machine aided design system；（5）Using data gathering system, which can provide the accurate location of engineering equipment and production facility；
（6）By mathematical model, computer aided design system and engineering equipment are be combined with each other and effectively control its dynamic.These skills
Art feature can provide reference for the design and application of China's air bench blasting.
The first step of bench blasting design is exactly the arrangement of blasthole, and the steel for shot method of explosion is between traditional elementary errors row
First according to the explosiveness of quick-fried area's rock mass, pitch-row and array pitch are empirically determined, it is random then by technical staff scene cloth hole
Larger, the main experience by technical staff is completed.
Summary of the invention
The purpose of the present invention is：Develop an adaptive steel for shot method based on computational geometry technology, can according to by
The precipice head line that in-site measurement obtains, adaptively arranges blasthole, to provide guarantee for bench blasting effect.
The present invention provides a kind of adaptive method for arranging of blasthole, including following operating procedure：
（1）Precipice head line coordinates and corresponding bottom of slope line coordinates are determined according to the region of bench blasting, pass through top of the slope and bench toe
Demarcate free boundary, the i.e. scope of freedom in bench blasting；
（2）Each bench blasting can only be a part of a step, determine explosion according to the scale of bench blasting and retain rock
The infinite boundary of body, is identified with -1；
（3）After the completion of free boundary and infinite boundary marking, free boundary is pressed specified array pitch pusher, obtains a series of rear push wheels
Profile, these contour lines are used to arrange blasthole, the pusher of free boundary according to the normal direction of the connected two lines section of each measuring point to
Amount is directed toward on the inside of quick-fried area, then every line segment is moved back by the direction of normal vector the distance of array pitch, then calculate move back it is every latter
The intersection point of line segment repeats the above process to get primary profile is moved back to free boundary, is full of entire quick-fried area until moving back profile
Until；
（4）After the completion of free boundary pusher, blasthole can be arranged on contour line in each move back, move back profile and nothing with every
The intersection point on poor boundary does a circle as starting point, by diameter of pitch-row, and the round intersection point with contour line takes remote when having 1 or 2,2
That intersection point from starting point, gained intersection point are a blasthole position, successively repeat aforesaid operations to every contour line, can be complete
At the steel for shot in quick-fried area.
During the pusher of free boundary, it is possible that polygon intersection region, i.e. redundant points.In order to eliminate redundancy
Point is only retained the point on scatterplot system outer profile, is eliminated redundant points to reach using the algorithm of convex hull in computational geometry
Purpose.

Specific embodiment
The present invention provides a kind of adaptive method for arranging of blasthole, and specific embodiment is as follows：
（1）The precipice head line coordinates and corresponding bottom of slope line coordinates of in-site measurement, precipice head line i.e. bench crest, by top of the slope with
Bench toe demarcates free boundary, i.e. the scope of freedom in bench blasting, and free boundary is according to the angle of the corresponding two lines section of measuring point
Size is divided into a free boundary or two free boundaries, that is, if on the inside of the area two lines Duan Bao that some measuring point is connected
Angle be less than or equal to 90 °, then be two free boundaries, identified respectively with 1 and 2, otherwise it is assumed that be a free boundary, use
1 mark；It is the purpose that free boundary divides into two：Convenient for finding the blasthole of first detonation；When only one free margins
It is when boundary, then random to formulate first blasthole detonated；
（2）The scale of bench blasting is to install standby ability decision according to production task index and shovel to work as, so each step
Explosion can only be a part of a step, thus, in adaptive steel for shot algorithm, also to provide and need explosion and reservation rock
The infinite boundary of body, infinite boundary are identified with -1；
（3）After the completion of free boundary and infinite boundary marking, free boundary is pressed specified array pitch pusher, obtains a series of rear push wheels
Profile, these contour lines are used to arrange blasthole；The backstepping of free boundary is：Calculate the connected two lines section of each measuring point
Normal vector is directed toward on the inside of quick-fried area, then every line segment is moved back by the direction of normal vector the distance of array pitch, then calculate and move back
The intersection point of every line segment repeats the above process afterwards to get primary profile is moved back to free boundary, until moving back profile full of whole
Until the area Ge Bao；
（4）After the completion of free boundary pusher, blasthole can be arranged on contour line in each move back, method is：It is moved back with every
Profile and the intersection point on infinite boundary do a circle by diameter of pitch-row as starting point, then the round intersection point with contour line has 1 or 2,
That intersection point far from starting point is taken at 2, gained intersection point is a blasthole position, successively repeats above-mentioned behaviour to every contour line
Make, the steel for shot in quick-fried area can be completed；
During the pusher of free boundary, it is possible that polygon intersection region, i.e. redundant points, in order to eliminate redundant points,
Using the algorithm of convex hull in computational geometry, i.e., only retain the point on scatterplot system outer profile, to reach the mesh for eliminating redundant points
's.
