摘要:
为预防西部浅埋煤层开采面临的顶板突水灾害,需要构建准确的突水预测模型来为煤炭安全生产提供有效保障。选取安山煤矿2001工作面为工程背景,以层次分析法与灰色关联法为理论依据,在顶板突水因素选择级分析的基础上,分别对地表汇水特征、含水层的富水性、隔水土层的隔水性、覆岩组合特征、开采扰动特征5个方面计算各影响因素的权重,并对其关联度进行计算,建立了定性与定量指标为一体的浅埋煤层顶板突水预测模型,然后结合实际工程参数进行顶板突水点及突水危险性预测。结果表明:安山煤矿2001工作面顶板突水危险性综合等级很低,但是该工作面地表汇水特征及覆岩组合特征对应突水危险级别相对较高,达到指标阀值时易造成突水事故。为避免相关灾害发生,工作面在实际回采过程中,矿方参考预测结果在雨季过沟谷地形段时加强了地表水和地下水的水量监控,并采取沟谷水提前抽放及封堵措施预防工作面顶板突水。
Abstract:
In order to prevent the roof water inrush in shallow coal seam mining in the west China,it is necessary to construct an accurate water inrush prediction model to provide effective guarantee for coal production safety.In this paper,the 2001 working face of Anshan coal mine was chose as the engineering background,with the analytic hierarchy process and grey relational analysis method as the theoretical foundation,on the basis of the selection hierarchy analysis,the weights of the influential factors were studied from five aspects:surface water catchment features,wateriness of the aquifer,water-resistant characteristics of aquiclude,combined influence of overburden and mining disturbance characteristics.Then the correlation degrees between water-inrush factors were calculated.Finally a prediction model on roof water inrush in shallow coal seam withintegration of qualitative and quantitative indexes was established.Further,combined with specific engineering parameters,we predicted the roof water inrush points and the water inrush risks.The results indicate that the risk comprehensive level of roof water inrush in 2001 working face is very low; however,the surface catchment characteristics and combined features of overlying strata corresponding inrush levels are relatively higher,showing that it is easy to cause water inrush when reaching the index thresholds.To avoid related disasters,the mine can strengthen the water quantity monitoring of surface water and underground water across the gully and low-lying areas in the rainy season,meanwhile,take advanced drainage and blocking measures to prevent roof water inrush.
