摘要
II6采区抽水资料较少,本文在合理利用采区内、外各种资料基础上,通过水文地质边界条件、充水水源、充水途径三个方面论述,正确掌握了II6采区的充水因素。西部为进水边界,东部为进水边界,南部F2断层为补给边界,北部F1断层为隔水边界。6～8煤间砂岩裂隙含水层(段)富水性弱～中等,10煤顶、底板砂岩裂隙含水层(段)富水性中等,均为采区直接充水水源。充水途径主要有构造裂隙、垮落带、导水裂缝带、断层及岩溶陷落柱以及未封闭好的钻孔等。最终达到了为采区涌水量计算、水害的防治及采区设计提供可靠地质资料的目的。
Based on the rational utilization in mining areas, all kinds of data, through the three aspects of hydrogeological boundary conditions, water source, water filling approach analysis, grasp the water filling factors ll6 mining area. The inlet boundary, east to the inlet boundary, south of the F2 fault to recharge boundary, North F1 fault is impermeable boundary. In 6-8 between coal sandstone fissure aquifer （section） water is weak - medium, 10 coal roof, floor sandstone fissure aquifer （section） water enrichment medium, are of direct water source. Water filling are the main approaches of structural fissure, caving zone, fractured zone, faults and karst collapse column and not closed well drilling. Eventually, as calculated in water inflow to provide reliable geological data and the design of mining area disaster prevention.
