Discussion Of Level Evaluation Of Solid Non-Energy Underground Mining Recovory Rate

Mining recovery rate as one of the important contents of the "three rates" indicators, reflects the utilization degree of underground resources, plays an evaluation of mining work quality and compare the role of management level of enterprise. This topic from the ministry of land and resources public welfare industry scientific research special "solid non-energy mineral resources comprehensive utilization of important technology standard research" neutron subject "solid non-energy mineral mining recovery rate evaluation research. Due to underground mining solid non-energy mineral resources stopping rate level at present in our country, there is no relevant departments to carry out the evaluation work, therefore has not been formed, and a reference method and standard, which cannot be mining enterprises for the underground mining recovery rate and degree of mineral resources development and utilization level of objective evaluation. Level of the evaluation for mining enterprises to improve the development and utilization of solid non-energy mineral resources mining recovery rate has a direct motivation and encouragement, for our solid non-energy mineral resources underground mining grade evaluation work to provide the reference to our country paying equal attention to exploitation and protection of resources and extend the service life of mineral resources is of great strategic significance to reality.This paper clear the definition of mining recovery rate, then find out the influence factors of mining recovery rate, analyzed the influence degree of various factors, from solid to underground mining recovery rate of dominant mineral resources mining method, the influence factors in mining method and structure parameters as the classification index, at the same time to collect domestic solid non-energy mine mining recovery rate of the data analysis, and then on this basis, select four classification method and interval estimation method in mathematical statistics as grade evaluation method, combining with the relevant laws and regulations, the department of policy documents and the national standards as the basis, of different underground mining methods the mining recovery rate of hierarchies, preliminary work out corresponding solid non-energy mineral resources underground mining recovery rate level evaluation standard, finally for mining enterprises to raise the level of underground mining recovery rate, put forward the corresponding regulation measures, management measures and the system of rewards and punishments.
