边帮压煤回采技术在露天煤矿开采中的应用研究

摘要：露天煤矿边帮压覆煤炭回采技术方式有多种，选用不当或技术应用不到位，均会对压煤回收的进度以及安全性产生直接影响。以某露天煤矿回采为例，首先，对回采压煤技术方案进行了比选，确定了回采设备，构建了压煤回采煤层及硐室的模型。其次，利用模拟分析的方式，确定了边帮压煤机回采作业的范围。最后，明确了回采顺序，并对边帮压煤回采作业与采剥工程的协调展开了分析，

Abstract： There are various techniques for backfilling coal in open-pit coal mines， and improper selection or inadequate application of these techniques can directly affect the progress and safety of coal recovery. Taking the mining of a certain open-pit coal mine as an example， firstly， a comparison and selection of coal pressing technology schemes were made， the mining equipment was determined， and a model of coal pressing mining coal seams and chambers was constructed. Secondly， the scope of the edge coal press mining operation was determined through simulation analysis. Finally， the mining sequence was clarified， and an analysis was conducted on the coordination between the edge coal press mining operation and the stripping engineering.

Key Words： Open-pit coal mine; Edge coal mining; Mining sequence; Technology application
