| 摘 要： | 研究采动影响对底板岩层的破坏范围,掌握矿压和水压对底板岩层作用的关系是煤矿防治底板水害的关键。团柏煤矿开采10煤和11煤,受到底板奥灰岩溶水的威胁,因此,以10煤为研究对象,采用煤层开采过程中底板监测钻孔的压水实验,研究采动影响范围和底板岩层的破坏深度。研究结果表明,10煤开采对底板岩层的破坏范围为10~12 m,横向影响范围40 m,峰值点位于6~20 m。该成果可为煤矿开采深部煤炭资源时进行底板突水预测预报提供技术支持。

| Abstract: | The 10th and 11thcoal seams in Tuanbai coal mine are suffering from the danger of water inrush from Ordovician karst water during mining.The key technical problems of coal mine floor water hazard control are the study on damaged areas of floor and the effect of ground pressure and water pressure on floor.Furthermore field measurement is reliable research method to master the floor damage regularity.The 10th coal seam was selected as the monitor object,the influence scope and fracture depth were studied by water pressure tests.The results show that,the damage depth of 10th coal is from ten meters to twelve meters,and influence scope are forty meters,the peak is from six meters to twenty meters. |
