Definitions

  • This invention is concerned generally with the setting of time delays in a sequence of explosive detonations.
  • Detonations are usually triggered electrically from a remote firing point, and many different electronic control systems have been developed to enable, as far as possible, theoretically desired time intervals to be achieved in practice.
  • the hole to hole separation in one row of charge is one of the critical factors affecting desired time intervals, and also the separation between adjacent rows of boreholes, and it would be desirable to provide a simple means whereby an operator on site could easily input appropriate data into a memory store, as he moves from one borehole to another e.g. when loading each hole with its pack of explosive charge and associated detonator, and then to be able to transfer such data to a remote control station.
  • This reference also discloses, in general, the use of GPS to generate precise positional data which is transmitted to the control unit.
  • An electrically operated rock blasting system according to the invention is defined in claim 1.
  • the electrically operated rock blasting system according to the invention has the advantage that the positions of the boreholes can be simply measured and stored by an operator as he/she moves from borehole to borehole. This data can then be simply transferred to the control station.
  • the data input device comprises a global positioning system (GPS) which is used to locate the positions of the boreholes.
  • GPS global positioning system
  • the GPS system provides a reliable and accurate absolute measurement of each of the boreholes of the series and hence the distance between them. The operator is not required to make measurements of the distances between boreholes, merely to place the GPS system close to each borehole in turn (usually when the borehole is being loaded) and make a measurement of position.
  • the data input device can comprise a portable keypad, the keypad preferably comprising number keys representative of different distances.
  • a site operator can carry such a keypad from one borehole to another e.g. during loading of the boreholes with the packs of explosive charges/detonators, and can enter borehole separation distance data as the operator moves from one borehole of the series to another.
  • a suitable input can easily be made by counting the number of paces involved in moving from one borehole to another or using some other convenient measure of length.
  • the data input device converts the distance data automatically to time interval data for subsequent down loading into the data store at the control station.
  • the data input device can be adapted to down load the distance data to the date store, the data store being pre-programmed to convert the distance data to time interval data to be set at the control station.
  • the rock mass site may be a quarry.
  • the invention may also be applied to formation of a tunnel through a rock face, in which case the boreholes will be spaced apart along a ring.
  • Preferably some suitable length measuring means is then used to measure the spacing apart between consecutive holes.
  • the invention therefore permits, by simple means, a site operator to be able to enter distance derived data into the control station, so that (after collating any other site dependent data), initiation of a sequence of detonations can take place at time intervals which approach, or come within close enough ranges to theoretically desirable time intervals for efficient utilisation of the explosive energy created by successive explosions in any particular site location.
  • the invention also contemplates use of an electronically controlled system, in which pre-programmed time delay intervals can be stored, and to allow operator-controlled modification of the time delays by inputting of distance-dependent data (between adjacent holes) which is converted to time delay modification of the programmed intervals.
  • FIG. 1 Shown in Figure 1 is a rock mass site 10, having a free face 11, and two rows of spaced boreholes 12 and 13. Into each borehole is introduced a detonation pack 14.
  • a detonation pack 14 comprising an explosive charge 15, and a detonator 16, the detonator 16 preferably being an electronic detonator.
  • the detonation pack 14 is located at a suitable depth below the surface within a borehole 17 so ensuring maximum effectiveness of the explosive charge 15.
  • the detonation pack 14 can be triggered or initiated into operation by a suitable signal along a line 18 from a control station 19.
  • the control station 19 is a remote firing station connected by lines 18 to a series of detonation packs 14 arranged in the boreholes 17 of rows 12 and 13.
  • the control station 19 is arranged to be capable of initiating sequential detonation of the series of explosive charges 15 of the detonation packs.
  • a data store 20 is arranged at the control station 19 and serves to receive different types of site data having an influence on theoretically desirable time intervals between successive detonations.
  • Critical site data which may be inputted includes the particular nature of the rock face to be fragmented, and further critical data is the physical distance separation between boreholes of successively triggered charges of explosives.
  • Figure 1 shows by reference d, a typical borehole separation distance between two successively triggered explosive charges.
  • the system of this embodiment of the invention further comprises a portable keypad 21, the keyboard having entry buttons 22, each representative of a particular measured distance between successive boreholes, for use by a site operator as he moves between successive boreholes of the series.
  • the keypad 21 has a memory store into which can be entered separate distance data between successive boreholes, and which is convertible into corresponding time interval data to be set at the control station 19.
  • the distance data entered by the operator would be determined simply by pacing out the distance between successive bore holes, working on an average stride of about 3 feet or a metre, and then the appropriate button 22 on the keypad 21 would then be operated.
  • the distance data entered (e.g. 5 metres), is then converted automatically to time interval data to be set at the control station 19.
  • This conversion takes place within the portable keypad 21 by provision of suitable preprogramming of the keypad, and is subsequently downloaded into the data store 20 at the control station 19.
  • the portable keypad takes into account other site critical data, for example the nature of the rock face to be fragmented.
  • the size of the boreholes may also be taken into account; if the holes are of a restricted nature and so require more delay time to effect the desired relief then the holes can be specified as greater than actual (or vice versa) to effect the most desired time interval.
  • the keypad 21 includes a barcode reader which is able to log required detonator firing sequences from individual detonators in each borehole, each being uniquely coded.
  • the distance data entered into the keypad may be downloaded into the data store 20, which is in turn preprogrammed to convert the distance data to time interval data.
  • the electrically operated rock blasting system according to the invention, as described above and shown schematically in the drawings, therefore provides, by simple means, for a site operator to be able to enter distance derived data into the control station, so that (after collating any other site dependent data) initiation of a sequence of detonations can take place at time intervals which approach, or come within close enough ranges to theoretically desirable time intervals between successive explosions in any particular site location, in order to achieve efficient utilization of the blasting energy.
