在毛主席革命路线指引下,我国煤炭工业发展很快.矿山所需的钢材日益增加.因此在煤炭生产中,寻求代钢途径,对支援农业机械化,加速社会主义建设,巩固无产阶级专政,具有重大的政治意义和经济意义.松藻煤矿现阶段,开采平洞以上煤炭,煤层倾角22°～32°.每个采区煤系底板茅口石灰岩内布置集中溜煤上山.煤炭利用自重运输.我矿曾先后用过搪瓷瘤槽、陶瓷溜槽、铸铁溜槽、薄板钢溜槽.由于煤炭生产的客观条件是地下作业,矿井水带酸性,产品运输量比较大,因此对溜槽的腐蚀、磨损
Under the guidance of Chairman Mao’s revolutionary line, the coal industry in our country has been developing rapidly with the increasing demand for steel in mines, so in coal production, it is seeking ways to replace steel with a view to supporting the mechanization of agriculture, accelerating the building of socialism and consolidating the dictatorship of the proletariat. Significant political significance and economic significance.Songzao coal mine at this stage, the exploitation of coal above the Pingdu coal seam angle of 22 ° ~ 32 ° coal mining floor Maokou limestone in each mining area to focus on the arrangement of coal slippery up the mountain.The use of dead weight coal transport. I mine has been used enamel trough, ceramic chute, cast iron chute, sheet steel chute.Because the objective conditions of coal production is underground work, mine water with acidity, product traffic is relatively large, so the chute corrosion, wear and tear
