【摘要】：根據(jù)五虎山煤礦近距離煤層群開采的特點(diǎn),在分析礦井瓦斯賦存和涌出規(guī)律、計(jì)算工作面瓦斯涌出量的基礎(chǔ)上,提出了"定向長(zhǎng)鉆孔區(qū)域預(yù)抽、鄰近層卸壓抽采、采空區(qū)瓦斯抽采"的適合近距離高瓦斯煤層群開采的分源瓦斯治理技術(shù)。該技術(shù)的應(yīng)用使得礦井瓦斯涌出得到有效治理,確保了采掘工作面的安全高效生產(chǎn)。
[Abstract]:According to the characteristics of short distance coal seam group mining in Wuhushan Coal Mine, on the basis of analyzing the law of gas occurrence and emission and calculating the amount of gas emission in the working face, the paper puts forward that "the region of directional long borehole is pre-pumped, the adjacent strata are discharged by pressure". Gas drainage in goaf is suitable for close distance and high gas coal seam mining. The application of this technology can effectively control the gas emission and ensure the safe and efficient production of the mining face.
