万福矿井充水水源分析及矿井涌水量预计

摘要

Through analysis on hydrogeological characters and mine water infilling factors of coal mine , it is consid-ered that main water filling sources are sandstone fissure aquifer of roof and floor in No .3 coal stratum and the third section of limestone karst fractured aquifer .By using "big well method", water inflow amounts of coal wells have been estimated, and normal mine inflow is determined as 279m3/h.It will provide believable basis for mine de-sign.%通过对井田水文地质特征及矿井充水因素的分析，认为矿井的主要充水水源为3煤层顶底板砂岩裂隙含水层及三灰岩溶裂隙含水层。采用“大井法”对矿井涌水量进行了预算，确定矿井的正常涌水量为279 m3/h，预算结果为矿井的设计提供了科学依据。
