Roadway Retention Technology - China

price: check with company for price

Advantages of staying along the empty road: (1) Can eliminate the section coal pillar to increase the production rate (2) Less one roadway to solve the problem of mining succession (3) Realize Y-type ventilation, reduce the gas concentration of the corner, and increase the safety Passage and drainage of goafs and adjacent sections, coal seam gas. High-water materials are filled along the roadway to achieve mechanized continuous filling along the empty roadway, which adapts to the rapid advancement of the working face. The speed of the 4~5m working face of Liulin mining is 8m/d, and the high-water material stays along the empty road. The small strength and good effect of the closed goaf have become the main way to support the roadway along the empty roadway. Our company successfully carried out the high-water materials along the empty roadway in the following conditions: fully mechanized top coal (Qian'an Group Gaohe Energy Company, Yuwu Coal Industry, roof with 3m thick coal seam), deep and large mining height (Jianjie Group) Haishiwan Coal Mine, Lingzhi Group Liujiazhuang Coal Mine, Xu Mining Group Sanhejian Coal Mine), composite roof (Fuxin Group Fuxin Mine, Xinyuan Mine, Changchun Group Xinchao Coal Mine), thick coal seam high gas (Coke Coal Group Jiuli Mountain) Mine), thin coal seam (Nanjing Coal Mine, Beisu Coal Mine, Huai'nan Mining Group Xieyi Mine, Xinzhuang Coal Mine), general conditions (Xu Mining Group Pangzhuang Mine and Jiahe Coal Mine, Xinwenyu Town Coal Mine and Pingdingshan Second mine).
