冒顶一直是煤矿井下开采工作最常见的,也是危害性最大的安全事故之一。如何在设计、开采施工过程中把握多元化因素,避免冒顶事故的发生,保障煤炭企业的生产效益,就显得至关重要。笔者结合刘庄煤矿151302的工程实例分析了大采高综采工作面局部冒顶的原因,采取针对性的处理方法 ,并制定了相应的控制措施,为大采高工作面处理冒顶提供了一些可以借鉴的经验。
Roof fall has always been the most common mine mining work, but also one of the most dangerous safety accidents. How to grasp the diversification factors in the process of design and mining construction, avoid the occurrence of roof fall accidents, and ensure the production efficiency of coal enterprises is of vital importance. Based on the engineering example of 151302 in Liuzhuang Coal Mine, the author analyzes the reasons of partial roof fall in fully mechanized fully mechanized mining face, takes the pertinent treatment method and formulates the corresponding control measures, Learn from experience.
