摘要
以大采高作业面片帮冒顶机理及控制为对象开展探究,结合具体工程实际,在全面分析煤壁片帮和顶板冒漏原理的基础上,就注浆加固控制措施进行总结分析,并对其实际应用效果开展分析,希望能够为其他矿井相似工程的开展提供借鉴和参考。
The mechanism and control of wall caving and roof fall in mining face with large mining height was studied.Combined with the actual project,on the basis of a comprehensive analysis of the principle of coal wall caving and roof fall,this paper summarized and analyzed the grouting reinforcement control measures,and analyzed the actual application effects,hoping to provide reference for the development of similar projects in other mines.
