摘要
通过对唐阳矿井煤层复杂地质条件下综放开采技术的系统分析,指出工作面遭遇冒顶和工作面变面是该条件下综放开采所面临的主要技术难题。在对综放工作面分析的基础上,提出了处理冒顶和工作面变面的主要技术途径和措施,在唐阳煤矿矿井的复杂地质条件下,成功的进行了综放开采的实践,实现了综放开采技术的突破,并取得了很好的的预期效果。
Through systematical analysis of fully mechanized caving mining technology in Tangyang Coal Mine seams under complex geo- logical conditions, the roof fall and changing surfaces in working tace are the main technical problems that fully mechanized caving min- ing face laces. Based on the analysis of fully mechanized caving face, the paper proposes major technical approaches and measures to deal with the changing surfaces of the face and roof fall. In Tangyang Coal Mine complicated geological conditions, the succuss practice is implemented to achieve breakthrough for mechanized caving mining technology, and gets good the expected effect.
