强含水层上充填开采煤炭资源的分析研究

摘要

强含水层上充填开采煤炭资源，与垮落法相比围岩应力变化、底板破坏深度等有本质区别。文章结合岱庄矿充填开采实践提出等效巷道宽度概念，探讨充填工作面底板安全隔水层厚度评价方法，通过合理确定等效巷道宽度，以此计算安全隔水层厚度、评价工作面开采安全性，为岱庄煤矿16煤开采提供理论依据。%The coal resource is iflled with strong water bearing stratum, has the essential difference with the caving method in surrounding rock stress change and bottom damage depth. According to Dai Zhuang mine mining practice, put forward the equivalent width of roadway, investigate the iflling working face safety aquifuge thickness evaluation method, by reasonably determining the equivalent width of roadway safety, in order to calculate the thickness of aquifuge, mining safety evaluation, to provide a theoretical basis for Daizhuang coal mine 16 coal mining.
