摘 要:
应用高位综放工艺回采煤柱资源对于已有38年开采历史的老矿来说是一种经济、高效的手段。其不仅有效的降低了万吨掘进率、降低了原煤成本，而且大大提高了矿井的资源回收率，取得了可观的经济效益。其在我矿22315综放工作面试验的成功不仅丰富了回采工艺技术，还为矿井长期稳产、高产以及延长矿井的服务年限具有重要意义。[著者文摘]

Abstract:
The application of elevated fully mechanized caving mining technology is an economical and efficient means for an old coal mine with an exploitation history of 38 years. It＇s not only effectively reduced the 10,000 tons＇tunneling rate and the cost of coal, but also greatly enhanced the recovery of the mine resources, and achieved considerable economic benefits. Its successful trail at the fully mechanized caving 22315 face not only enriches the mining technology, but also is of great significance in the aspects of the long - term stable production, high yield and the lifespan prolonging of the mine.[著者文摘]
