Technical field
The utility model relates to a kind of single-point and excites the advanced means of detection of multipoint reception mine laneway, belongs to colliery earthquake physical prospecting technical field.
Background technology
Along with the fast development of China coal industry, each mining area exploitation degree of depth constantly increases, the geologic hazard undertaken in recovery process is increasing, the gas explosion in colliery, tomography lead water, the seriously disaster such as permeable, the loss of life and personal injury caused and financial loss are very surprising. Therefore, the safety in production of coal is the most important thing of coal industry. In order to ensure coal mine production safety, geophysical prospecting equipment before production, is utilized to be very important to the abnormal geologic framework of forecast in advance.
The advanced detection equipment of mine laneway and method are numerous, and traditional detection method has that MSP seismic wave detects in advance, DC electrical method detects in advance and transient electromagnetic method detection etc. in advance. Use these equipments and method to carry out advanced detection to have some effects but there is many defects. MSP seismic wave detects in advance and uses two three component acceleration or velocity-type detectors, shot point is used repeatedly to substitute multiple collector during construction, also it is exactly that a shot point substitutes a collector, single-point excites single-geophone receiver, completed the requirement of many collectors reception by multi-point shooting, and excite generation seismic wave energy, phase place all not identical with frequency each time, so the earthquake data differences received is bigger, consistence is not good, and this can affect the explanation of analysis software. In addition, will receiving valid data, often carry out repeatedly exciting on a shot point, this seismic wave is effective to produce many thinking of seismic wave similarity, and the workload that operates like this is very big.
Detect in advance as employing DC electrical method and transient electromagnetic method, the useful signal produced due to it is very weak, be subject to atmospherics and ground unrest impact very big, the probability collecting useful signal is less, and this brings totally unfavorable impact to the explanation of analysis software. These two kinds of methods are relatively more effective to the detection of low-resistivity medium, and detection structure effect is not obvious. So a urgent need rational detection equipment and effective detection method are very necessary.
Practical novel content
For solving the technical problem that prior art exists, it is simple that the utility model provides a kind of structure, and reasonable in design, good stability, the single-point that accuracy rate is high excites the advanced means of detection of multipoint reception mine laneway.
For achieving the above object, the technical scheme that the utility model adopts is that a kind of single-point excites the advanced means of detection of multipoint reception mine laneway, comprise main frame, collector and explosive source device, described explosive source device is formed primarily of "painted-face" character in opera and pallet, the signal interface of described main frame is connected with multiple collector by signal cable, by triggering, cable is connected the trigger interface of described main frame with explosive source device, wherein the trigger interface T1 of main frame is connected with pallet, and the trigger interface T2 of main frame is connected with "painted-face" character in opera.
Preferably, the quantity of described collector is at least two, and is evenly distributed on the both sides in tunnel.
Preferably, described collector is fixed on anchor pole by web member, and the anchor rod anchored side in tunnel is helped.
Preferably, distance between described collector and roadway floor is 1m��2m, distance between adjacent collector is 1m��3m, the collector nearest from tunnel face and the distance of tunnel face are 5m��10m, pallet and multiple collector are on one wire, distance between pallet and nearest collector is 1m��5m, and the distance between pallet and tunnel face is 5m��10m.
Compared with prior art, the utility model has following technique effect: the utility model adopts and once excites the seismic wave of generation to gather reception for multiple collector simultaneously, the unstable repeatedly exciting and producing seismic wave useful signal can not only be overcome, and can also ensure that the energy of seismic wave, phase place and frequency are consistent, thus improve the accuracy rate that mine laneway detects in advance.
In addition, identify that seismic wave useful signal is by repeatedly repeating to excite, on a shot point, the seismic wave produced, it is believed that what similarity was many is useful signal. Therefore single-point is adopted to excite multipoint reception, as long as namely exciting once, just can observe the seismic waveshape of all acceptance points, as long as exciting the significant wave that just can obtain all acceptance points for several times like this on a shot point, compared with this bit receives with multi-point shooting, easy construction, working efficiency improves.
