1.
In order to solve the problems,according to the roof characteristic in Yanmazhuang Coal Mine,tensile groove fracture method was used to split the main roof with pre-splitting blasting hoping to affect the first weighting,and stations were built to observe the mine pressure changing and roof displacement during the period of working face′s mining.
为了解决突出煤层坚硬顶板回采工作面顶板悬露不垮和采空区爆破放顶易引起瓦斯爆炸的问题,针对演马庄矿顶板特性,采用拉槽断裂法对基本顶进行预裂爆破,以干预初次来压;建立测站,观测了工作面回采期间的矿压变化和顶板位移。
5) fault groove
断层槽地
补充资料:微孔膜电解槽
分子式:
CAS号:
性质:改进的电解食盐溶液隔膜电解槽。用聚合物制成微孔膜代替石棉,具有平滑而均匀的表面,可使两极间距缩小,从而有效地降低槽电压。目前尚处于工业试验阶段。
