| 摘 要： | 罗园井田地处淮南煤田中段南缘，阜风逆冲推覆构造部位，井田内含水层（组）由新生界松散砂层孔隙水、二叠系砂岩裂隙水、石炭系太原组石灰岩岩溶裂隙水、奥陶系岩溶裂隙水和寒武系岩溶裂隙水五个含水岩组组成，水文地质条件简单～中等。在分析井田充水因素的基础上，指出灰岩与煤岩层对口部位是突水发生的主要地段。采用生产矿井比拟法，预算开采4-1～13-1煤层时，正常涌水量为316m^3／h，最大涌水量755m^3／h；利用地下水动力学法预算矿井正常涌水量为328m^3／h，太原组岩溶水突水量为798m^3／h。根据本井田煤层陡倾斜及含水层间强水力联系的特点，说明矿井防治水工作难度较大，在今后的矿井设计和生产过程中应有针对性地采取综合水害防治措施。

| Abstract: | A series of late Jurassic-early Cretaceous coal-bearing basins have developed in southern Songliao Basin and distributed regularly. To take the Liaohe fault as a boundary can be divided into east and west two depositional areas： east part is mainly fluvial facies, representatives have Tiefa, Baoli basins; west part is mainly lacustrine facies, representatives have Xieersu, Changchengwopeng basins. Through structural, deposition environmental and coal accumulative characteristic analyses of known basins put forward the future coal looking orientation： in the east of Liaohe fault part give precedence to northeastern part of Tiefa mining area, Liangzhong and Cilushu basins; in the west part give precedence to Lanao and Qianjiadian basins. |
