摘要
目前,三软煤层支护强度大的问题,一直是困扰煤矿生产和安全的重大难题。永华能源有限公司嵩山煤矿在2103综采工作面上顺槽3#段进行了支护优化设计,经过长时间的矿压观测分析,本次支护优化设计解决了三软煤层短时间内返修率高的问题。
At present, the problem of three soft coal seam supporting strength, has been a major problem that plagued the coal mine production and safety. Yonghua Energy Co., Ltd. Songshan coal in 2103 fully mechanized face along the groove 3 segment for the optimization design of support. After a long time of mine pressure observation and analysis, the branch support optimization design to solve the＆quot;Three Soft＆quot;coal seam in a short time repair rate high question.
