Coal-controlling structural characteristics and the coal-bearing law of Lücaogou coal mine in Qinghai Province
Through the collation and analysis of the geological work carried out in the Lücaoshan area,the seven coal-controlling faults developed in the Lücaoshan area were systematically sorted out,and the geological structure properties and coal-controlling mech-anism affecting the occurrence of the main mineable coal seams in the Lücaogou coal mine were summarized in detail.The results indi-cate that,The Lücaogou coal mine is divided into two coal-controlling structural blocks in the east and west,with the F3 fault as the boundary.The geological structure of the eastern block is complex,and the geological structure of the western block is medium.The G3 coal seam is a medium-thick and locally recoverable unstable coal seam;the G2 upper coal seam and the G21ower coal seam are medium-thick and extremely thick coal seams.In the eastern and western blocks,the G2 uppercoal seam is locally recoverable unstable coal seam and the G2 lower coal seam is locally recoverable relatively stable coal seam;the G1 coal seam is a medium-thick-thick coal seam developed in most of the region.In the eastern and western blocks,it is mostly recoverable unstable coal seam and relatively stable coal seam,respectively.The F coal seam is an extra-thick and locally recoverable unstable coal seam developed in the F1-F2 fault zone.
