一般认为苏南煤田地质构造复杂,煤层稳定性差,水文地质条件较为简单。实际上,苏南煤矿自1959年建井以来,通过二十多年的建井和生产开采,不少矿井先后出现井筒、煤面、掘进头的透水现象,多次造成局部停产,甚至整个矿井被水淹没,给国家造成一定损失。就苏南煤矿透水资料分析,它既有煤层上履含水层的来水,也有煤层底板来水;就煤层本身而言,它既有受古河床
Generally believed that the South Jiangsu coalfield complex geological structure, coal seam stability is poor, hydrogeological conditions is relatively simple. In fact, since the construction of the well in 1959 in Sunan Coal Mine, many wells have successively appeared the permeable phenomenon of wellbore, coal face and driving head after more than 20 years of well construction and production and mining, causing many to stop production on several occasions and even the whole mine Was flooded, to the country caused some loss. On the south of SuNan coal mine pervious to water analysis, it not only has the water layer on the coal seam water, but also the coal floor water; on the coal itself, it has both ancient river bed
