摘要

本文通过对煤层顶底板地层地质及其灰岩含(隔)水层的分析,根据钻孔数据资料中煤层底板所承受水头压力,计算得出采区煤仓位置的安全隔水层厚度;确定采区煤仓的布置层位;确定采区煤仓有效容量;结合矿井实际确定煤仓的布置型式;计算确定煤仓的尺寸等数据;针对煤仓的顶底板岩性,提出针对性煤仓支护措施。
        Based on the analysis of the top and bottom stratum geology of the coal seam and the analysis of the limestone containing(separated) water layer, according to the head pressure of the coal seam floor in the borehole data,the thickness of the safe aquifer in the position of the coal bunker in the mining area is calculated; determine the layout level of the coal bunker in the mining area; determine the effective capacity of the coal bunker in the mining area;determine the layout type of the coal bunker in combination with the actual mine; calculate the data such as the size of the coal bunker; In view of the lithology of the top and bottom of the coal bunker, the targeted coal bunker support measures were proposed.
