摘要
山浪煤矿开采山西组3上煤层,侏罗系砂岩裂隙含水层、煤层顶板砂岩裂隙含水层是矿井主要充水含水层,根据两含水层之间隔水层厚度进行分区,运用"充分冒裂"理论、"层间越流补给"理论,"层间裂隙绕流"理论、"差值运动分量"理论等研究充水机理,将这些理论应用于工作面涌水量预测起到较好的效果。
the nmuntain sea c.oal mining coal seam of shanxi grnup 3, the Jurassic sandstone fraeture aquifer, coal seam roof sandstone fraetureaquifer are major mine water filling aquifers, according to the thickness of water-resisting layer partition between the aquifer, on the basis oftire theory of ／＂fillty crackV＇, ／＂layer between the flow of supplies／＂ theory, the theory of interlayer fissure flow around and the theory ofdifferential mtion component water filling mechanism, applying these theories to working face water inflow prediction has a good effect.
