摘要
本文根据印度浅埋厚煤层、坚硬顶板的条件 ,提出了恒底综采与二次综放联合开采的技术方案 ,并对其优点和可行性进行了论证 ,还提出了坚硬顶板断裂线位置的监测方法 ,该开采方法对防止坚硬顶板来压时的动压冲击 ,保证生产安全 。
This paper presents a technological plan-a combined longwall mining method integrated fully mechanized longwall mining along seam floor first with fully mechanized longwall sublevel caving mining afterwards according to the conditions of Indian shallow thick seams under hard roof rocks and proves its advantages and feasibility. It also introduces amethod for monitoring the location of fracturing line of hard roof rocks. The method is of important value for application in preventing the dynamic impact when hard roof weighting occurs and ensuring the safe production.
