彬长矿区孟村煤矿煤层埋深较大，地质构造复杂，基建期间多次发生冲击地压显现，严重影响安全生产。本文以孟村煤矿中央大巷为研究对象，采用理论分析、实验室实验、数值模拟和现场监测等手段对深部构造区多巷掘进冲击地压诱发机制与防控技术进行了研究。 通过实验室试验和冲击倾向性分析，认为4号煤层具有强冲击倾向性。采用原位测量法测得首采区地应力场水平应力大于垂直应力，以水平应力为主，最大主应力值在26～38MPa之间，属于高及超高应力区。通过现场监测发现巷道开挖后，围岩呈分区式破裂，形成了“破裂区-完整区-破裂区”的组成结构，由浅入深范围为0~4.3m，4.3~9m，9~13m。结合实际地质条件，采用FLAC3D软件进行数值模拟，结果表明，褶曲、断层构造会增大掘进巷道的支承压力，如巷道掘至褶曲轴部时垂直应力集中系数达到了1.75，增加了29.6%。指出了孟村煤矿深部构造区冲击地压的诱发机制：孟村煤矿掘进巷道的冲击地压由围岩静载荷引起；该静载荷由基础静载荷和附加静载荷构成，基础静载荷是由围岩分区破裂产生的变形差形成的，附加静载荷由褶曲、断层等构造引起；当静载荷值大于围岩冲击启动临界值时，巷道发生冲击地压。 根据诱发机制，提出了矿井掘进期间“以疏通和卸压相结合”的综合防控技术，即以优化巷道布局来疏导煤体内分区变形差导致的基础静载荷，同时以大直径钻孔卸压来释放构造区内巷道围岩的附加载荷。建议后期应沿方位角145～171°设计巷道或设计巷道轴线与方位角145～171°方向夹角小的巷道。大直径钻孔卸压的孔深应不低于7.71m，孔间距宜取0.7m，钻孔最优布置形式为单排布置，并制定了构造区掘进巷道局部钻孔卸压技术方案。

The Mengcun Coal Mine in Binchang Mining Area has a large coal seam depth and complex geological structure. During the construction period, rock burst has been occurred many times, which seriously affects the safety of production. In this paper, the driving roadway of Mengcun Coal Mine's central roadway and working face is taken as the research object, and the mechanism and prevention and control technology of rock burst induced by multi.roadway driving in deep structural area are studied by means of theoretical analysis, laboratory experiments, numerical simulation and on.site monitoring. According to the laboratory test and the analysis of the impact tendency, the No. 4 coal seam has the strong impact tendency.Horizontal stress is the main stress field in the first mining area measured by in.situ measurement. The maximum principal stress is between 26 MPa and 38 MPa, which belongs to high and super high stress area. Through field monitoring, it is found that after excavation, the surrounding rock is divided into zones from shallow to deep, forming a structure of “rupture zone.complete zone.rupture zone”. The range from shallow to deep is 0-4.3m, 4.3-9m and 9-13m. Combining with the actual geological conditions, the numerical simulation is carried out by FLAC3D software. The results show that fold and fault structure will increase the supporting pressure of driving roadway. For instance, the vertical stress concentration factor reached 1.75 when the roadway was excavated to the folded crankshaft, which increased by 29.6%. The mechanism of rock burst induced by multi.roadway driving in deep structural area of Mengcun Coal Mine is pointed out. The load source of impact is divided into foundation static load and additional static load. The foundation static load is caused by the difference of deformation caused by different fracture zones of surrounding rock under multi.roadway layout. The load generally exists in the surrounding rock of roadway. The additional static load is caused by folds, faults and other structures. After superimposition, the static load level of surrounding rock of roadway increases. The relationship between the static load value and the critical value of surrounding rock impact initiation determines whether the rock burst occurs or not. According to the induced mechanism, the comprehensive prevention and control technology of "combining dredging and pressure relief" during the mine excavation is put forward, that is to optimize the tunnel layout to dredge the static load of the foundation caused by the deformation difference of the partition in the coal body, and to release the additional load of the surrounding rock of the tunnel in the structural area by the large.diameter borehole pressure relief. It is suggested that in the later stage, the roadway should be designed along the azimuth of 145.171 ° or the roadway with a small angle between the axis of the design roadway and the azimuth of 145.171 °. The hole depth of large.diameter drilling should not be less than 7.71m, and the hole spacing should be 0.7m. The optimal arrangement of drilling is single row arrangement. The technical scheme of local drilling pressure relief for driving roadway in structural area is formulated.
