subject: The Tenet Of Mine Equipment Selection [print this page] The production equipment for mining choice,its specification and performance is varied.How to organize the design,manufacturing and selection rationally,then make the mining equipment
manufacturing enterprise with less investment,high efficiency,adaptability,and low operating costs,is a more complexed issue of great importance. Production practice tells us, during the process
of the choosing equipment and combinations matching process, the following aspects must be considered: Resource conditions Including the ore body geometry and its position in space, the quality
and grade of ore, mechanical properties of the ore and rock, and other mining technology conditions,etc. Terrain and traffic conditions Including the mining landscape,the geographical environment
around the ore, mountains and rivers direction,the main traffic arteries category (railway, road, sea and air) and route specifications. Weather conditions Including the highest temperature and
lowest temperature in different seasons,the length of the rainy season and rainfall, snowfall period, snowfall and snow cover duration, the wind and cloud distribution, the wind level and
direction, day and night length ratio. Energy conditions Including the type of energy and capacity,energy supplies,energy supply stability and reliality ,the self-sufficiency of self-enery used in
the equipment Mine size and the yield range The parameters directly affect the level and quantity of production equipment specifications. To make the production equipment adapt to the mine scale,
and the technical and economic benefits from the early stages of building mine to built mine from the early stages to each production stage. Equipment techical and economic aspects To choose the
best production equipment,the total principle requirements are:advanced technology,practical production,reliabilty,easy modification,ecomomic and rational. When selecting one quipment,we must
consider the following aspects: Good use,which means that can meet the production process requirements,strong adaptability, convenient operation, advanced technical performance, high efficiency,
ease to match with related equipment. Good reliability,which refers to the reliable working precision,low failure rate,high attendance,long average life in the case of playing fully its function.
Good maintainability, which refers to reasonable equipment structure,high degree of components standardization and generalization, good interchangeability,easy inspection, testing and maintenance
Good economy, which means less energy consumption, low maintenance cost,most economic life circle operation, good comprehensive economic efficiency. Environmental and safety technology Refers to
the production equipment in the work of 'human relations ' coordination, safety devices properly, does not occur 'run, run, drip, drain'phenomenon, no emissions of harmful substances into the
surrounding Technology policy Refers to giving priority to domestic equipment and self-made equipment when purchasing production equipment, not ch
