摘要
以同煤集团四老沟矿大采高工作面8407作为研究对象,针对其复杂的地质条件,制定合理的矿压观测方案,根据观测结果,总结出工作面矿压显现规律及其两巷矿压显现特征,有针对性地制定了相应技术措施,为矿井实现高产、高效、安全生产创造了有利条件。
For the Complicated geological conditions, the fully mechanized coal mining face with high cutting height in Si Lao Gou mine is researched by the reasonable observation programmes. And the Ground pressure of work face and the Ground pressure characteristics of both sides are concluded, by which the action are taken to provide the advantage for the aim of the Highyield, efficient, safe produetion.
