摘要
针对华阳一矿掘进工作面现场实际情况,优化巷道布置方式,改进施工工艺,提出了在巷道顶板完好时采取一次支护紧跟煤头、二次补强锚索(隔1排布置2根)滞后40 m补打的分次支护的方案,并基于此研究顶板离层情况和变化规律,为支护设计和施工组织提供数据支撑和理论依据。
According to the actual situation of the heading face in Huayang No.1 coal mine,the roadway layout is optimized and the construction technology is improved.When the roadway roof is in good condition,the scheme of primary support followed by the coal head and secondary reinforcement anchor cable(2 cables arranged in a row)with a delay of 40 m is proposed.Based on this,the roof separation and change law are studied to provide data support and theoretical basis for support design and construction organization.
