断层破碎区煤岩体失稳机制与注浆耦合控制研究
Research on Instability Mechanism of Coal and Rock Mass and Coupling Grouting Control in Fault Fractured Zone
【摘要】 以清水营煤矿复杂煤层工作面穿越断层区域的工程应用为背景,分析了断层区开采扰动诱发断层活化机制及控灾减灾模式,确定了内部注浆耦合控制方法,改善了煤岩体自承载能力,提高支护结构与煤岩体相互作用和适应能力,实现了安全开采。本论文对复杂煤岩体开采扰动下安全开采提供了理论依据,为今后宁东矿区和全国类似条件煤炭能源安全高效开发提供了理论与工程借鉴。
【Abstract】 Taking the complex coal seam working face of Qingshuiying Coal Mine crossing the fault area as the engineering background,this paper studies on mechanism of disturbance-induced fault activation in fault area and disaster control-reduction model,gives the internal grouting coupling control method,ameliorates the selfcarrying capacity of coal and rock structure,improves the support structure and coal rock interaction and adaptability,and achieves disaster reduction and safe mining. This research provides a theoretical basis for safe mining under the disturbance of complex coal rock structure,also provides engineering reference for the future development of coal energy security in Ningdong Mining Area and similar conditions in China.
