| 摘 要： | 烧变岩是活鸡兔矿井的顶板充水含水层,直接威胁着矿井的生产安全。烧变岩分布广泛,裂隙发育程度在垂向上规律明显:下剧—中强—上弱。其富水性除受构造、地形和地貌的控制外,还决定于是否接受其他含水层的补给。烧变岩水水质良好,符合国家饮用水标准,供排结合是矿井水综合利用的有效方法。

| Abstract: | The coal seam roof of Huojitu Mine is the burnt rock,which is the water impregnated aquifer,is dangerous to mine safety.The burnt rock distributed widely.The regularities of fracture development are vertically apparant,for example,the fractrues decrease upwards.The water abundance of the rock is controlled not only by structures,geographic and surface features,but also controlled by the recharge condition from other aquifer.The water quality of the rock can meet the drinking water standards of the state.Therefore,the water control combining dewatering and water supply is the effective way. |
