阐述了复合型动力灾害发生过程机理,通过具体案例,分析了复合型动力灾害现象;针对复合型动力灾害提出了微震监测、敏感指标预测方法及煤层注水、卸压爆破灾害防治技术。考察效果表明:煤层注水提高了煤体含水量,提高了煤体塑性;卸压爆破解除了应力集中,减小了冲击危险性,同时结合卸压抽放,可以有效地防治复合型动力灾害。 The mechanism of compound dynamic disasters is expounded. The complex dynamic disasters are analyzed through concrete cases. The microseismic monitoring, the prediction method of sensitive index and the prevention and control of coal seam water injection and pressure relief blasting are proposed for composite dynamic disasters. The investigation results show that the water injection of coal seam increases the water content of coal and improves the plasticity of coal; the pressure relief blasting relieves the stress concentration and reduces the impact risk. Combined with relief pressure drainage, it can effectively prevent and cure compound dynamic disasters.
