摘要
近年来由于煤炭资源的不断开采,矿井深度增加导致煤层地质条件不断恶化,尤其是急倾斜煤层的回采工作,对开采工艺有着极高的要求.结合当前急倾斜煤层开采工艺现状,通过分析急倾斜煤层回采参数,提出一种新型斜坡短臂采煤工艺,为该类复杂型煤层的开采提供借鉴.
Abstract
In recent years,due to the continuous mining of coal resources and the increase in mine depth,the geological conditions of coal seams have been continuously deteriorating,especially in the mining of steeply inclined coal seams,which have extremely high requirements for mining technology.Based on the current status of mining technology in steeply inclined coal seams,a new type of slope short arm mining technology is proposed by analyzing the mining parameters of steeply inclined coal seams,providing reference for the mining of such complex coal seams.
