梁宝寺矿井掘进巷道构造附近煤层冲击显现机理及防治措施

冲击倾向性是煤岩体发生冲击破坏的固有能力，断层、褶皱、相变等构造诱发冲击地压的机理为构造应力与采动应力叠加，避免应力叠加是防治构造控制型冲击地压的有效途径。本文结合粱宝寺矿井掘进巷道煤层冲击显示特征，分析其形成原因，进而探究冲击地压作用机理，根据现场条件及时采取卸压措施，起到了很好的效果。该课题的研究对冲击危险性评价、冲击地压防治理论研究及现场治理等具有参考意义。

The Coal Seam Burst Apparent Mechanism and Prevention Measures of Mine Excavation Roadway Nearby Structure of Liang Baosi Mine

Burst tendency of coal rock impact failure is the inherent capability,the superposition of tectonic stress and disturbance stress is the essence of coal burst induced by geologic structures such as faults, folds and transformations; the effective approach to prevent tectonic-controlled coal burst is to avoid the stress superposition. This article combines excavation roadway seam impact display characteristics of Liangbaosi mine, analysis of the cause of its formation,then research into the rockburst mechanism,according to the site conditions,taking timely relief measures,played a very good effect. The study of the subject has the reference value to shock hazard assessment ,rockburst prevention theory research and scene governance.
