| 摘 要： | 基于新庄孜煤矿近距离煤层群全为突出煤层的情况，选择突出危险性程度较低的、煤层厚度只有0．8m的B10煤作为近距离煤层群开采首采层，即关键保护层工作面。采用一面六巷的瓦斯治理技术，并在66310工作面成功应用，实现了煤层群首采关键层煤与瓦斯安全高效共采。研究成果可为低透气性高瓦斯煤层群卸压开采提供指导。

| Abstract: | Based on the condition of close outburst coalseams in XinZhuangzi coalmine, the B10 coalseam of 0.8m thick and low outburst risk is applied to firstly mining key seafn in close multi- coalseams. The technology of one panel with six roadways is used in gas control for 66310 panel, real- izing safe coal production and high efficient methane extraction. The results can be served as a refer- ence for destress mining in multi-coalseams of low permeability and high gas emission. |
