松藻矿区开采二叠系上统龙潭组煤层,主采位于煤系中部的全区可采的M8煤层,为石灰岩岩溶充水矿床。M8煤层采面突水后支架和刮板运输机被压死、或淹没采区水仓,水灾处理难度大、经济损失大。在研究矿区及M8煤层水文地质条件的基础上,认为M8煤层采面充水水源主要是长兴组岩溶裂隙水和上保护层采空区水,充水通道主要是冒落裂隙和构造裂隙带。总结了M8煤层采面涌水量及其持续时间、出水形式等特征,提出了采场布置、探放水、排水、支护、匀速推采五个方面的采面防治水对策。
鬆藻礦區開採二疊繫上統龍潭組煤層,主採位于煤繫中部的全區可採的M8煤層,為石灰巖巖溶充水礦床。M8煤層採麵突水後支架和颳闆運輸機被壓死、或淹沒採區水倉,水災處理難度大、經濟損失大。在研究礦區及M8煤層水文地質條件的基礎上,認為M8煤層採麵充水水源主要是長興組巖溶裂隙水和上保護層採空區水,充水通道主要是冒落裂隙和構造裂隙帶。總結瞭M8煤層採麵湧水量及其持續時間、齣水形式等特徵,提齣瞭採場佈置、探放水、排水、支護、勻速推採五箇方麵的採麵防治水對策。

The Upper Permian Longtan Formation coal seams are being mined in the Songzao mining area, the main mineable coal seam M8 is situated in the middle part of coal measures. Coalmines in the area are limestone karst water filling mines. After water bursting in?to stoping faces, support and scraper conveyer will be crushed, or stoping area water sump submerged with difficult flooding processing and huge economic losses. Based on mining area and coal M8 hydrogeological condition studies, considered that coal M8 stoping face water filling sources are mainly from Changxing Formation karst fissure water and upper protective seam gob water;water filling chan?nels mainly have caving fissures and structural fissures. Coal M8 stoping face water inflow and duration, water filling features have been summarized, and water controlling countermeasures put forward from five aspects of stope layout, water prospecting and dewater?ing, water drainage, supporting and steady speed progressive extraction.
