摘要
地下井采空区是制约露天复采的影响因素,采取可靠的探查方法,探索井工开采改露采复采老巷采空区防治标准作业流程,研究重大灾害综合防治措施,最大程度地减少由采空区、空巷等因素带来的安全隐患,有效防止煤矿瓦斯事故发生,科学指导生产实践。
The underground goaf is the influencing factors of restricting open-pit mining, the mine adopts the reliable exploration methods to explore the prevention standard operating procedures of underground mining reform open-pit mining old goaf, to maximize eliminate safe risks caused by goaf empty area, which effectively prevent the occurrence of coal mine accidents and scientifically guide production practice.
