摘要
显德汪矿历年瓦斯鉴定均为瓦斯矿井,随着开采深度的增加,九采区二号煤层采掘期间局部出现瓦斯较大涌出现象,给瓦斯管理带来一定难度。针对以上现象,该矿决定在该区域工作面采掘期间实施深部较大涌出危险性鉴定、专项治理措施、瓦斯预警系统等瓦斯综合治理技术,确保该区域工作面的安全采掘。
Xiandewang Mine had been identified as gas mine for years, with the increase of mining depth, part of No.2 coal seam of 9th mining area appeared with gas pouring during mining, which brought difficulty to gas management, based on the phenomenon above, the mine decided to implement deep wells larger risk identification, special measures, gas early warning system, etc, gas comprehensive control technology to ensure safety mining in working face of the region.
