| 摘 要： | 为有效控制煤层底板带压开采突水发生,同时解决突水系数法评价底板突水的局限性,引入灰色模糊聚类法综合评价煤层底板突水危险性。以袁店煤矿101、102采区为例,通过对10煤层水文地质条件、底板充水水源和充水通道深入分析,提取评价煤层底板突水危险性关键指标,综合考虑岩溶裂隙发育、地质构造、隔水层厚度、裂隙含水层富水性、灰岩含水层厚度5个突水主控因素,并进行底板突水危险性分区。结果表明：101采区底板突水危险性较小,102采区危险性较大。建议对102采区局部富水地段进行注浆加固,以达到防治突水的目的。

| Abstract: | To control the coal floor water bursting during mining under safe water pressure of aquifer,and solve limitations in coal floor water bursting assessment using water bursting coefficient at one time,the gray-fuzzy clustering is introduced to assess coal floor water bursting hazard comprehensively.Taking the Nos.101,102 winning districts in the Yuandian coalmine as example,analyzed No.10 coal hydrogeological condition,floor water filling source and water channel in depth,picked up key indices in the hazard a... |
