摘　　要：蒋庄煤矿构造较为复杂,厘清矿区内构造发育规律并揭示其构造控煤作用,有利于该矿的高效和安全生产。利用数理统计方法,对矿井断层及褶皱进行系统分析,并归纳总结了不同构造组合对主采煤层的控制作用。结果发现,矿区内断层与褶皱以NE—SW向为主,普遍发育的正断层以70°~79°的高角度切割褶皱,且断层落差普遍大于20 m,逆断层较少发育。分析发现断层的平面延伸长度越长,其落差越大。矿区中部发育连续宽缓褶皱,褶皱区内断层发育较少,西北部有燕山期闪长玢岩侵入煤层。以研究区构造组合特点,归纳总结出4种构造控煤样式:①地堑、地垒式构造控煤样式;②阶梯式断层构造控煤样式;③断褶型构造控煤样式;④断层与岩浆侵入型构造控煤样式。其共同的最大特点是将煤层切割为走向NE的狭长型断块。The structure of Jiangzhuang Coal Mine is relatively complex.It is beneficial to the efficient and safe production of the mine to clarify the structural development law and reveal its structural coal controlling effects of coal.The faults and folds in the mine were systematically analyzed by using mathematical statistical methods,and the controlling effects of different structural combinations on the main mining coal seams were summarized.The results show that the faults and folds in the mining area are mainly orientated NE-SW,the commonly developed normal faults cut the folds at a high angle of 70°~79°,and the fault throw is generally greater than 20 m,and the reverse faults are less developed.It is found that the longer the plane extension length of the fault,the greater its throw.In the central part of the mining area,continuous wide and gentle folds are developed,and there are few faults in the fold area.In the northwest,there are Yanshanian diorite porphyrite intrusion coal seams.According to the characteristics of structural combination in the study area,four types of structural coal control styles were summarized:①graben and horst structure coal control style;②ladder fault structure coal control style;③fault-fold structure coal controlling style;④fault and magmatic intrusion structure coal controlling style.The biggest common feature is that the coal seam is cut into narrow and long fault blocks with strike NE.
