南山矿盆底区南翼15^#层一分段瓦斯综合治理

Gas Comprehensive Treatment at First-stage of South 15~# Coal Seam in Bottom of Nanshan Coal Mine

通过南山煤矿盆底区南翼15#层一分段综放工作面生产实践,总结了特厚煤层综放开采过程中瓦斯综合治理办法。特厚煤层通过采前预抽瓦斯及边采边抽瓦斯,达到一次采全高,减少了掘进工程量,提高了煤炭生产的经济效益。

Through production practice at fully mechanized caving face at first-stage of south 15# coal seam in the bottom of Nanshan Coal Mine,summarizes the gas comprehensive control measures at fully mechanized caving face in the special thick seam.In the special thick seam mining,through pre-draining gas before mining and draining during mining,can mine full-seam,reduce the tunneling and improve the economic benefit of coal production.
