摘要
随着矿井开采深度和开采强度的增大,瓦斯灾害问题日益严重,影响矿井的安全生产。文章利用实测瓦斯数据和地勘瓦斯地质资料,对赵固二矿一盘区的瓦斯赋存规律进行了分析,得出了该矿一盘区二1煤层瓦斯含量增加梯度为2.21mL/g.r/100m;进一步分析了影响控制赵固二矿二1煤层瓦斯赋存规律的埋藏深度、地质构造、水文地质条件和煤层露头等因素,并对矿井的瓦斯治理工作提出了建议。
As the strength and depth of mining increasing, gas plays a growing effect on the mine safety. In this paper, with measured gas data and the coal mine gas data, the gas distributed rule in Zhaogu No.2 Coal Mine is analyzed, It is concluded that the gas content gradient of II1 coal seam in NO.1 area comes to 2.21mL/g·r/100m. Further the effects for gas rule in II1 coal seam are analyzed, such as burial depth, geological structure, hydrological condition and coal seam outcrop, the recommendations to the gas control are put forward.
