峰峰矿区是以岩溶裂隙水为主的大水矿区。由于受煤系地层底部奥陶纪石灰岩水(以下称奥灰水)的严重威胁,致使该区占总地质储量约50％的太原组下三层煤不能得到正常开采。因此,只有查明矿区奥灰水的水文地质条件,才能为综合开发治理奥灰水,解放下三层煤提供技术上可行、经济方面有效的方法和途径。 Fengfeng mining area is based karst fissure water-based mining area. Due to the serious threat of Ordovician limestone water (hereinafter referred to as Ordovician limestone water) at the bottom of coal-bearing strata, the third coal layer of the Taiyuan Formation, which accounts for about 50% of the total geological reserves, can not be properly mined. Therefore, only by identifying hydrogeological conditions of Ordovician gray water in the mining area can we provide technically feasible and economically effective methods and ways for the comprehensive development and control of Ordovician gray water and the liberation of the lower three-layer coal.
