在煤矿生产过程中,井底的所有水向水仓集中,通过流水巷中的水沟集中向水仓流动的过程中,由于矿井水中含有大量的煤泥颗粒,在水沟里会很快被煤泥颗粒淤满,淤塞的煤泥影响了煤矿安全生产及运输。煤矿井下流水巷水沟里的煤泥一直以来是靠人工清挖,用铁锹把煤泥清挖出来,再将煤泥运到巷道两旁堆放。待煤泥晾干后人工装入矿车运到地面。煤泥人工清挖,需要工人多并且矿工劳动强度大,效率低,工作环境又很恶劣。随着科技的进步和劳动力成本的提高,采用液压自动控制和短臂伸缩机构及液动挖斗机械形式,是清挖煤矿井下流水巷水沟煤泥的最佳途径之一。
In the process of coal mine production, all the water at the bottom of the well is concentrated in the sump. During the process of flowing the ditches of the sump into the sump, the mine water contains a large amount of slime particles and is rapidly Slime particles silt, silt slime affected the safety of coal production and transport. Slurry in the underground coal mine drainage gutters has always been excavated by hand. Shovels are used to dig out slime and coal slimes are piled on both sides of the roadway. After the slime to be dried manually loaded into the car transported to the ground. Slime manual excavation, the need for workers and miner labor intensity, low efficiency, the working environment is very bad. With the progress of science and technology and the increase of labor cost, adopting hydraulic automatic control, short-arm telescopic mechanism and hydraulic bucket mechanical form is one of the best ways to clear the ditch slime of underground coal mine.
