为解决综放工作面频繁发生大面积压架事故的问题,对同煤塔山煤矿综放工作面压架案例进行了分析,认为地质因素、支架工作状况和工作面管理是造成综放开采压架的主要原因。通过压架原因分析,从开采前划定压架预警范围,采取合理的采放高度,加强现场管理,提高支护质量,工作面矿压预警,对离层水进行疏放,合理的支架阻力选型等方面开展压架防治工作。
In order to solve the problem of frequent large-scale ram accidents in fully mechanized coal caving face, the author analyzed the pressure-supporting cases of fully mechanized caving mining face in Tashan coal mine and concluded that the geological factors, The main reason. Through the analysis of the reason of pressure racking, the pre-racking pressure racking warning range was determined, a reasonable height of mining and placing was taken, the on-site management was strengthened, the support quality was improved, the pressure of working face was pre-stressed, the stratified and rational strata resistance Selection and other areas to carry out pressure control work.
