摘要
根据施工的水文孔与三带孔的具体资料及该区与滕县煤田南部区域资料,在充分分析第四系、风化带及煤层顶板水文地质及工程地质特征的基础上,提出了露头煤柱留设方案及矿井水防治措施,并确定了2 煤开采上限,解放了大量的煤炭呆滞储量,延长了矿井服务年限。
In the light of concrete data collected from hydrographic holes and inspection holes for overlying layers,as well as the regional data of the study area and the southern Tengxian coalfield,the Quaternary weathered zone,the hydrogeologic and engineering geologic properties of seam top are fully analyzed. Based on study results,the plan of cropping coal pillar leaving and underground water control is put forward.The upper mining limit of Seam No.3 is determined,as result the coal reserve is increased and the life of the mine is extended.
