破碎顶板条件下综采工作面搬家工艺研究

Study on the moving process of fully mechanized face under the condition of broken roof

大同鹊山高家窑煤矿5202工作面在开采过程中遇到地质构造复杂、顶板破碎、来压明显等情况。为实现快速搬家,提高开采速度和煤炭回采率,通过钻探、巷探等技术手段,探明工作面情况,采用注浆加固,架设钢棚等方式,实现工作面快速安全撤架,为煤矿的高效安全生产提供了保障。

in the mining process, the 5202 working face of Gao Jia Shan Gao Jia Yao coal mine has encountered complicated geological structure, broken roof and obvious pressure and so on. In order to achieve rapid relocation, improve mining speed and coal recovery rate, through drilling and lanes and other technical means, we can identify the working face, use grouting reinforcement and erect steel shed to achieve fast and safe withdrawal of the working face, which provides a guarantee for the efficient and safe production of the coal mine.
