林南仓井田充水特征分析及防治水建议

林南仓井田水文地质特征主要表现为煤系地层上覆第四系冲积层孔隙强含水层,下伏奥陶系石灰岩岩溶强含水层,矿井涌水以煤系地层砂岩裂隙水为主,矿区软岩地层发育,岩性条件对矿井充水影响大,突水点常见于构造部位,涌水规律表现为集中小出水点较多,出水形式多为滴、淋水。针对这些情况,提出了强化水文地质基础工作、提高矿井防治水工作的针对性、突出构造部位突水防治、加强工程地质条件研究等防治水建议。

Feature analysis and water prevention advice of Linnancang coalfield

The hydrogeological characteristics of Linnancang coalfield are mainly characterized by the strong water-bearing layer of the Quaternary alluvium overlying the coal strata and the strong water-bearing layer,limestone karst of the Ordovician system underneath,the water gushing from the mine was mainly sandstone fracture water of the coal strata,the soft rock strata were developed in the mine area,the lithological conditions had a great influence on the water filling of the mine,the water gushing points were commonly found in the tectonic parts,the water gushing pattern was concentrated with more small water gushing points,and the water gushing forms were mostly dripping and drenching.In response to these situations,water control suggestions were put forward to strengthen the basic work of hydrogeology,improve the relevance of water control work in mines,highlight the prevention and control of sudden water in tectonic parts,and strengthen the study of engineering geological conditions.
