摘  要:针对部分薄煤层工作面通过增大滚筒截深来提高开采效率和减少工人劳动强度的需求,建立了折算单刀开采效率计算模型,对开采效率提高影响较大的装煤效果和牵引速度深入研究分析,并提供两个具有代表性的应用案例。本文研究为矿方研究其通过增大截深提高开采效率的可行性提供分析思路,同时也对薄煤层大截深开采技术的发展有一定的指导意义。In response to the demand of some thin coal seam working faces to improve the mining efficiency and reduce the labor intensity of workers by increasing the cutting depth of the drum,a calculation model of the converted single-tool mining efficiency is established.The loading effect and haulage speed,which have a significant impact on the improvement of mining efficiency,are deeply studied and analyzed,and two representative application cases are provided.This paper provides an analytical idea for the mine to study the feasibility of improving the mining efficiency by increasing the cutting depth,and also has certain guiding significance for the development of the large cutting depth mining technology in thin coal seams.
