露天煤矿地下采空区勘查与治理技术研究

Research of exploration and treatment technology in the Open-pit Coal Mine goaf

以平朔东露天矿开采境界内的老空区群为工程实例,提出了露天煤矿地下采空区(空洞)综合勘查与治理技术路线,从空间参数的查明、治理方法的选择、最佳治理时间的确定到爆破参数的设计,详细分析了典型空腔体的治理思路与方法,对指导露天矿生产和维护作业人员及设备安全具有十分重要的意义。

Taking the goaf group of Pingshuo East Open-pit Mine mining area as the engineering instance, the article proposed underground goaf integrated survey and treatment technology. From identification of space parameters, the choice of treatment method, the determination of optimal treatment time to the design of blasting parameters, the author analyzed the methods of typical cavity, which had significance for guiding the production and the maintenance safety of operating personnel and equipment.
