Study on Mining Technology and Equipment Matching at Fully-mechanized Face for Large Mining Height One Pass Cutting Coal Mining

神化集团补连塔矿32301工作面煤层厚7.17～8.05m,煤层倾角1°～3°,设计工作面沿煤层走向布置,采高为4.5～6.1m。工作面沿底板推进,采用倾斜长壁一次采全高采煤法,全部垮落法管理顶板,工作面设计月产量为1 Mt。工作面投产后,采煤工艺和设备配合良好,各设备配套运转稳定,达到了工作面月产量1Mt的设计能力,最大产量为2008年1月,产煤1.1028Mt,技术经济效益显著。

At 32301 Face of Qilianda Colliery, Shenhua Group Co. , with seam thick 7. 17-8.05m, seam inclination angle 1°-3°, layout of designing face is along seam trend, mining height is 4.5 -6.1 m. Coal face promoting along floor, inclined longwall one pass cutting coal mining and fully caving coal mining method is adopted to manage roof, coal face designing yield is 1 million tons monthly. After coal face put into operation, mining technology and equipment matching are better, every equipment matching operates smoothly, up to designing capacity of coal face yield 1 million t monthly, the largest yield is 1.28 million t, Jan. 2008, and technical economic benefit is significant.
