Comprehensive mining face roof management practice in Huipodi Coal Mean

本文首先对回坡底煤矿的31302工作面支架前梁一直到煤壁段顶板和支架以及煤壁的受力情况进行了分析,然后创建了"梁"结构理论模型,与此同时,对支架前梁到煤壁段顶板冒顶的原因进行了阐述,对回坡底煤矿31302工作面的冒顶起因进行了解释,最后提出解决综采工作面冒顶的相应措施,以期为解决该类问题提供参考依据。

This paper first of31302working face support beam before until the coal wall section of the roof and support as well as the stress of the coal wall are analyzed,and then created the theory of"beam"structure model,at the same time,to support the first beam to the coal wall roof caving are expounded,the cause of roof for the interpretation of the31302working face roof caving cause,finally put forward the corresponding measures to solve the fully mechanized working face roof caving,in order to offer reference basis to solve the problem of the class.
