Shanxi Coal Gangue Ecological Disposal Mode Study

The coal gangue is the coal production auxiliary product, calorific value is low, the ingredient is complex, which is one kind "tastelessness food, hates to discard something", "weak" resources. Formerly, besides the minority calorific value high gangue was used, the massive low heat value gangue is compelled to store up, not only waste resources, but also invades the land, air pollution, resident's health has the harm to the mining area around, carries on the comprehensive utilization and ecology handling urgently needed. Initiates circulate the economy in our country, the development "two types" the society, the change economic growth way, under the promotion economic society sustainable development big background, taking the comprehensive utilization and solves gangue ecology handling of the coal gangue has the important theory significance and the practice value.This article chose as Our country Energy Base Shanxi Province as the region of study, took the gangue ecology handling pattern as the object of study, using investigates and studies, The quantitative analysis and the qualitative analysis unify, the theoretical analysis and the empirical analysis unifies and so on; to Shanxi Province, gangue's use handling situation, existence's questions, ecology handling methods, ecology handling modes, ecology handling benefits and policy suggestions and so on, have carried on a more systematic elaboration, which provide the model for Shanxi, our country and other region's gangue handling.(1) Analyzed the present situation of coal gangue resources and the handling in Shanxi Province, pointed out:Large capacity coal gangue and mine pit quantity is numerous in Shanxi Province, the region was more scattered, but which have produced the giant gangue resources, at the end of 2009 accumulated stores up the quantity to amount to 613,339 wt, estimated that at the end of 2015 might accumulate increases 1,006,150wt; But the present handling rate is only 30%, ecology handling rate must be lower than this digit; The gangue ingredient is complex, the type is diverse, which increased the difficulty of the use and the handling; Inappropriatly storing up, possibly causes the air pollution, destroy the water body, occupy the land and other secondary disasters.(2) Has discussed theories and the methods of the gangue ecology handling, pointed out: Gangue ecology handling is different with general handling, which must take ecological economy, ecology repair, circulation economy as the basis and so on, followed classified centralism handling, converting into resources first to handle principles and so on, used the ecology Landfill, directly using, the rendering industry, entire journey management and so on 4 methods carries on. (3) Take circulates economy and the ecology industry chain as the instruction, take the even new moon mining area as the example, and experimentally has constructed 3 kinds of ecology handling industrial modes. the calorific value high gangue Suits to "the gangue - electricity generation - building materials","the gangue - elect and wash - the utility extraction" and so on ecology industry chain handling patterns; To the low heat value gangue and the tunneling gangue, may suit to fill the mine pit and the collapse area, the formation "the gangue fill in the ditch makes-the ecological agriculture, fish breeding and poultry raising, medicine plant" the ecological agriculture industry chain handling pattern; Abandons the mine pit, gangue greening area and Agricultural areas of ecological tourism of gangue, Suit to extension the industry chain, developed eco-tourism industry handling pattern.(4) Using the qualitative and quota method, analyzed the latent benefit which ecology handling produced in Shanxi Province. Pointing out:The gangue's comprehensive utilization and ecology handling, may have the considerable economic efficiency in Shanxi Province, Estimates, the sales revenue of the gangue comprehensive utilization is approximately more than 953 hundred million Yuan, only "35" period, the gangue electricity generation accumulation output value may amount to 480,6 million Yuan and to gain 48,0millionYuan, which has the considerable contribution to the mining area economic growth; The social efficiency mainly displays is increasing the employment opportunity; Environment benefit aspect, Mainly displays in new building land, reduces the emissions of SO2(5) The thesis gives relevant measures about the specific technology and national policy to solve the problems in coal refuse ecological disposition. The thesis points out that our government should simplify the approval procedure, inspire the enterprise to develop technology about coal refuse, afford rational concessions for the projects about coal refuse, and set up special financial aid to hold out those projects. All those measures are the important indemnify for the coal refuse disposition.
