Research and Application of Intelligent Powerful Coal Winning Equipment in Thin Coal Seam
According to the actual mining technical conditions of No. 9 coal seam working face in Jushan Mine,this paper puts forward the selection requirements of high reliability,intelligence and adaptability of coal winning machine in the working face. Based on the analysis of the main parameters of drum cutting depth,mining height,drum diameter and installed power rating of the coal winning machine,MG330/730-WD intelligent powerful coal winning machine is determined to be used. The main technical parameters of the equipment are given,and the main technical characteristics of short machine body,short rocker arm,wide machine body and high energy product ratio and intelligent control system are analyzed and applied to field practice. The practice shows that the equipment has good application effect and low failure rate,which can meet the re-quirements of safe and efficient mining of thin coal seam.
