百善井田被动式左旋双帚“S”型构造成因机理及其应用

ON THE MECHANICS OF BAISAN COAL MINE LEFT HANDED “S” SHAPED STRUCTURE SYSTEM AND APPLICATION

文章通过对百善井田地质构造特征及其成因机理分析研究，揭示出百善井田孤立含煤盆地为一位于特定构造部位，历经两期以上地质构造运动叠加复合，形成的被动式中心对称左旋双帚“Ｓ”型构造。进一步根据地质构造复杂程度和开采技术条件，将整个井田划分为两两对顶相似的四个预测区段。不仅为煤矿安全生产取得了较好的经济效益和社会效益，而且为中国东部区域地质构造学科宝库添加了一块砖瓦。

The author studied the structural feature of Baisan Coal Mine and its developping mchanics, found out the isolated coal bearing hasin locate a special structural setting,deformed in, at least, two structural cycle. The deformation overlay molded its appearance as left handed“S” shaped center symmetry structure system. Based on structure complexity and mining tecquical situation, the author classfied the mine field as two pair structural prediction area, which could be applied to direct safely mining. Meantime, it’s a contribute to the study of area geological structure in East China.
