摘要
在斜沟煤矿之前3个放顶煤工作面收尾方案的基础上,尝试一种新的收尾方案,创新采用了打探测孔和测标高建模型的方式,兼顾了煤炭回收率和回撤通道支护难易程度,确保了采煤工作面与回撤通道准确贯通。。
Basing on three fully mechanized caving working face finishing programmes in xiegou coal mine,tries a new finishing programme, combines coal recovery and return channel supporting difficulty, uses innovatly the way of constructing probe hole and elevating measurement, establishing model, makes sure accurate penetration of the fully mechanized caving working face and return channel.
