摘要
结合安太堡露天矿可采煤层赋存条件,选用EML边帮采煤机,利用三维地质软件计算边帮煤压覆资源储量,理论计算确定了边帮采煤支撑煤柱宽度,将边帮采煤技术应用到安太堡露天矿进行可行性分析。结果表明:压覆资源储量满足边帮采煤机成套设备年生产能力要求;利用EML边帮采煤机成套设备,可实现采硐内无人作业,安全高效回收边帮压覆煤炭资源。
Combining with the occurrence conditions of minable coal seam in Antaibao Open-pit Mine,the article selects EML slope coal mining machine to calculate the reserves of slope coal overlying resources by using three-dimensional geological software,and determines the width of slope supporting pillar by theoretical calculation.The article carries out feasibility analysis by applying slope mining technology to Antaibao Open-pit Mine.The results show that the complete set of equipment of EML slope coal mining machine can realize the unmanned operation in the mining tunnel and safe and efficient recovery of the slope overlaid coal resources.
