摘要
应用理论分析等手段研究综放开采过程中采场上方覆岩离层裂隙发育变化规律,阐述采场上方离层裂隙带的范围,分析了采空区离层裂隙带的空隙渗流特性。研究结果应用于工程实践取得了良好的经济技术效果。
With the theoretical analysis and other means, the paper studied the cracking development variation law of the separated strata in the overburden over the fully mechanized coal caving mining face. The stated the area of the cracking zone in the separated strata over the coal mining face an analyzed the cracking wandering features of the cracking zone in separated strata over the goaf. The research results has applies to the projects with excellent benefits.
