煤矿采空塌陷区危险性预测模型构建及其防治措施

采矿因素、地质因素等因素影响煤矿矿井采空塌陷区危险性预测结果，为了获取准确的煤矿采空塌陷区危险性预测结果，构建煤矿矿井采空塌陷区危险性预测模型。选取某省煤矿矿区作为研究区域，选取下沉系数与水平移动系数作为构建煤矿采空塌陷区危险性预测模型的参数，采用T-S模糊方法构建煤矿矿井采空塌陷区危险性预测模型，通过修正预测模型的模糊子集隶属函数更新预测模型，提升煤矿矿井采空塌陷区危险性预测精度。所构建模型输出煤矿矿井采空塌陷区危险性预测结果为中等，针对预测结果提出采用合理的采煤方式、合理避让、加强边坡监测3项煤矿矿井采空区塌陷防治措施，为煤矿矿井开采后防治采空区地面塌陷提供指导。

Establishment of risk prediction model for goaf subsidence area of coal mine and its prevention measures

Mining factors,geological factors and other factors affect the risk prediction results of coal mine goaf collapse area.In order to obtain accurate risk prediction results of coal mine goaf collapse area,a risk prediction model of coal mine goaf collapse area was built.The coal mine area of a province was selected as the research area,the subsidence coefficient and the horizontal movement coefficient were selected as the parameters of the risk prediction model for the goaf collapse area of coal mine,and the T-S fuzzy method was used to build the risk prediction model for the goaf collapse area of coal mine.The prediction model was updated by modifying the membership function of the fuzzy subset of the prediction model to improve the prediction accuracy of the risk of the goaf collapse area of coal mine.The risk prediction result of the goaf collapse area of the coal mine outputted by the model was medium.According to the prediction result,three prevention measures for the goaf collapse of the coal mine were proposed,namely,reasonable mining method,reasonable avoidance and enhanced slope monitoring,to provide guidance for the prevention and control of the ground collapse of the goaf after the mining of the coal mine.
