摘要
根据荥巩煤田生产矿井积累资料表明:该地区二1煤是煤与瓦斯突出严重的地区。谷山井主井及风井井筒揭煤前所作的瓦斯压力测定结果以及其结果与以前地质资料的对比分析,进一步验证了谷山井二1煤层瓦斯含量高,具有煤与瓦斯突出危险性,为今后安全施工及生产提供了技术依据。
according to aecumulating data of coal mine in xinggong coal field, Outburst of mine and gas about the Ⅱ 1 coal seam is serious in the area. Before main shaft and air shaft revealing coal in Gushan coal mine,the measure on methane pressure is finished,which is compared with previous geologic informatics. That methane content about the Ⅱ1 coal seam is high is further verified and have fatalness of mine and gas outburst in Gushan coal mine,Technical basis is provided with safety in production and construelion in the future.
