Abstract

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.
