The invention discloses a coal mine rock mass similar material drilling peeping detection system and method. The system comprises a rack, a drilling device, a washing mechanism, a drilling peeping mechanism and a monitoring module. The drilling device comprises a base, a sliding assembly and a drilling assembly. The washing mechanism comprises an air gun and an air compressor. The drilling peepingmechanism comprises an inserting rod, a camera and a lighting lamp. The method includes the following steps that 1, a coal mine rock mass similar material three-dimensional model is erected; 2, the drilling device is mounted, and drilling points are arranged; 3, the coal mine rock mass similar material is drilled; 4, drill holes are flushed; 5, the height of a fissure zone is determined. The change of the height of the fissure zone and the change of the height of a fissure zone gas enrichment region can be accurately simulated in the coal seam recovery process, and therefore reference is provided for gas extraction in the fissure zone in the exploitation process of a coal rock layer and reduction of the gas concentration.
Description
technical field [0001] The invention belongs to the technical field of drilling peep detection for similar materials of coal mine rock mass, and in particular relates to a drilling peep detection system and method for similar material of coal mine rock mass. Background technique [0002] In the process of coal mine production, the development height of the fissure zone above the coal seam after the coal seam is mined is studied, and the development height of the fissure zone is mastered, so as to reasonably determine the method of gas drainage and gas concentration reduction in the fracture zone during the coal seam mining process. It is of great significance to reduce outburst accidents and safe production in coal mines. [0003] Considering the complexity and high cost of actual coal mine core sampling, usually according to the actual coal mine rock mass structure, combined with the similarity criterion, a kind of coal and rock mass similar material is made, and a similar ...
