矿井提升运输授课教案(国外英文资料) Mine hoisting Lecture class: wangjijie The first section of the mine raises the description of transport Mine elevation transportation system is an important part of mine production, its main task is: (1) the underground mining of coal, coal gangue and other things need to be sent to the ground, through transport transport equipment to the bottom in the roadway, reuse lifting equipment to the ground. (2) the underground production, safety, maintenance and other required equipment, equipment, etc, the use of lifting equipment, from the ground through the wellbore to the bottom, and then after the roadway needed to transport equipment to the site, for safety, production services. (3) lifter. The mine transportation system is divided into three basic parts, namely the transportation system, the horizontal transport system and the shaft hoisting system. The mine improvement system can be classified into the following categories according to different classification methods: (1) the improvement of the main well and the secondary well shall be promoted according to the purpose. (2) it is divided into vertical well and incline well increase according to the Angle of lifting shaft. (3) according to ascend machine types are divided into spiral wound (is divided into single cylinder and double drum) ascension ascension and friction type, spiral wound ascension can be used for vertical and inclined system, friction elevator is used only for vertical shaft hoisting system. (4) the drag type is divided into the communication drag lift system and the dc drag lift system. (5) ascending, cage hoisting and series of cars are divided into ascending containers. Second, mine improvement system Mine shaft lift and the power equipment in inclined lane transportation hoist motor, according to the belt roller diameter, diameter greater than 2 m according to hoist, less than 2 m in diameter as ascending little winch. Mine lifting equipment mainly has lift, lifting rope,
