摘要:
在研究大佛寺煤矿煤层气赋存地质背景基础上,探讨了影响低煤阶煤层气开发的主要地质因素,结合地面煤层气井产气量相关地质因素综合分析,优选了大佛寺煤矿煤层气开发的主控制地质因素指标及次级控制因素指标,采用加权指数法通过计算评价对象的综合得分,以综合得分高低判定煤层气开发优劣区,研究认为,大佛寺煤矿4#煤层煤层气以中等有利开发区为主,主要位于井田中东部,面积约占整个煤层气评价区面积的54%,有利开发区主要位于井田东部,面积较小,约占整个煤层气评价区面积的7.92%,不利开发区主要位于井田西部,面积约占整个煤层气评价区面积的42.04%.评价结果对大佛寺煤矿低煤阶煤层气地面开发有重要参考价值。
Abstract:
On the basis of the research on CBM occurrence geological background in Dafosi coal mine,the major geological factors influencing low-rank coal CBM development were explored.Combining with the comprehensive analysis of the related geological factors for ground CBM production,we optimally selected both primary geological controlling factors and secondary control factors indexes for CBM development of Dafosi coal mine,calculated comprehensive scores for evaluated object using the weighted indexes,and determined the merits of CBM development by the comprehensive scores.Research results show that No.4 coal seam CBM in Dafosi coal mine is mainly moderate favorable zone,located mainly in the mid-eastern field,accounting for about 54% of the entire CBM evaluation area.The favorable development zone is situated in the eastern field with smaller area,which accounts for about 7.92% of the entire CBM evaluation area,and the unfavorable development zone is mainly in the western field,accounting for about 42.04% of the entire CBM evaluation area.The evaluation results are of an important reference for ground mining of the low-rank coal CBM in Dafosi coal mine.
