| 摘 要： | 根据大量钻孔和矿井生产资料，对淮南煤田13一i煤层顶板地质条件进行了详细的分析和研究，结果表明，煤层顶板的沉积环境及沉积特征对顶板的稳定性起主要控制作用。煤层小构造和顶板岩性组合等因素影响顶板稳定性的局部变化．分流河道砂岩是稳定性最好的顶板岩性。厚层分流间湾泥岩顶板的稳定性次之，泛滥平原泥岩顶板和决口扇、潮坪砂岩顶板为不稳定或中等稳定．

| Abstract: | The detailed studies on the roof geological condition of No.13-1 coal-bed in Huainan coalfield were carried out based on the drilling and mining materials, it was shown that the sedimentary environment and features mainly control the stability of coal-bed roof, the other factors such as mini-structures and rock assemblies give local impacts on it.The thick sandstone complex of distributary channel is the most stable roof rock, and the thick mudstone roof rock formed in the interdistributary bay secondaryly.The interbedded of sandstone and mudstone roof rocks developed from floodplain, crevasse and tidal flat sandstone are unstable or medium stable. |
