小型矿井瓦斯抽放的研究与实践

小型矿井薄煤层进行瓦斯抽放不多见,对其所取得的效果及其稳定程度等问题均没有经验可参考。该矿因煤层开采深度大,煤层薄,断层等地质构造原因,较之以前煤层瓦斯含量大,因此,需进行瓦斯抽放。2008年,在安全生产的前提下同比提高产量30%,创该矿井历史最好水平。

Study and Practice of Small-scale Mine Gas Drainage

Small-scale coal mine gas drainage is rare,the results and its stability have't experience for reference.Because of the big mining depth,thin coal seams and faults est.geological structural reasons,coal seam gas content is larger than the previous.Therefore,the gas drainage was made.In 2008,in the premise of safe production,the production increased 30% and reached to the highest level in the history.
