13191工作面矿压显现规律研究及对策

Study on Strata Behavior at 13191 Working face and Its Countermeasures

利用矿压观测分析技术对13191工作面周期来压规律、强度及步距进行分析监测。通过15天左右的下井矿压观测,对工作面回采过程中矿压显现进行了较为详细的观测得出了结论,并制定了针对性措施,确保了矿井安全回采。

In view of 15-day strata control observation on the rules,strength and distance of periodical pressure at 13191 working face,a detailed conclusion of the strata behavior during extraction has reached and measures have been adopted to ensure the safety of extraction.
