| 摘 要： | 伊宁苏勒萨依井田各煤层为低变质烟煤,瓦斯含量相对较低,以二氧化碳-氮气带为主。在垂向上,瓦斯含量随深度增大总体呈增加之势;在横向上,瓦斯含量自西向东有逐渐升高趋势,其富集地段主要分布于皮里青背斜南冀68线和72线南部一带,建议在矿井开采中,重点监测该地段。严禁超通风能力生产,防止瓦斯大量聚集而引起事故。

| Abstract: | The coal strata in Sulesayi coal mine in Yining city are low metamorphic bituminous with rather low gas content,while carbon and dioxide belt are rather rich.In the vertical direction,the overall gas content has the tendency which will increase with the increased depth;while in the horizontal,the gas content will gradually increase from west to east.Its accumulation sections mainly distributed in No.68 line and south part of No.72 line in southern Piliqing anticline.It is suggested that this section should be regarded as the monitoring focus.The production under the over ventilation conditon should be prohibited to prevent accumulation of gas which can cause a large number of accidents. |
