摘要
为了提高综采工作面收尾通道顶板稳定性,保证工作面搬家回撤任务安全高效运行,文章对马兰矿12704工作面的收尾通道进行了优化支护,这种收尾技术在12704工作面的应用,取得了良好的应用效果,为今后综采工作面合理选择收尾方法提供了理论依据,且总结说明了综采工作面收尾期间的主要注意事项,为综采工作面收尾提供了实践依据。
In order to improve the roof stability of the closing channel of fully mechanized mining face and ensure the safe and efficient operation of the work face moving and withdrawing,the paper optimized the support of the ending channel of 12704 working face in Malan coal mine.The application of this kind of ending technology in 12704 working face has achieved good application effect,which provides theoretical basis for reasonable selection of ending method in fully mechanized mining face in the future The main points for attention during the closing period of fully mechanized mining face are explained,which provides practical basis for the end of fully mechanized mining face.
