极近距离煤层工作面停采支护工艺

Stop-picking Support Technology of Coal Seam Working Face at Very Close Range

随着煤矿开采的推进,不可避免的要面临极近距离煤层的回采,由于层间距过小,无法采用常规的支护手段来维护机道顶板,这就给煤矿的安全生产带来极大的隐患。通过采用综合安全措施,保证了综采工作面停采期间顶板的完整性。

With the development of mining in coal mine, close-distance coal seam mining has inevitably become a common occurance, and due to shortness of the layer spacing, conventional roof support method cannot be used to maintain the roof panel, which brings huge hidden trouble to coal mine production. By adopting integrated safety measures, the integrity of the roof during stop-mining period is guaranteed.
