薄煤层智能开采技术研究现状与进展

Research status and progress of intelligent mining technology in thin coal seam

薄煤层占我国煤炭总储量的20%。由于特殊条件(例如狭窄的采矿空间)的限制,薄煤层的开采效率非常低,情报量低,仅占煤炭总产量的10%。根据薄煤层的层理条件变化以及不同的采矿需求以提高工厂生产率,降低压力和加快工作面恢复。系统分析了我国薄煤层开发,长壁综采设备,智能化采矿技术,半煤公路开挖,超细煤层开采技术开发项目的研究现状。

Thin coal seam accounts for 20%of China's total coal reserves.Due to the limitation of special conditions(such as narrow mining space),the mining efficiency of thin coal seam is very low and the amount of information is low,accounting for only 10%of the total coal output.According to the changes of bedding conditions of thin coal seams and different mining needs,to improve plant productivity,pressure is reduced to accelerate face recovery.This paper systematically analyzes the research status of thin coal seam development,longwall fully mechanized mining equipment,intelligent mining technology,semi coal highway excavation and ultra-fine coal seam mining technology development projects in China.
