Evaluation of selected target areas on CBM ground mining for low-rank coal of Dafosi coal mine
摘要
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 se-lected both primary geological controlling factors and secondary control factors indexes for CBM develop-ment of Dafosi coal mine,calculated comprehensive scores for evaluated object using the weighted inde-xes,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 develop-ment 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.关键词
