The Application Research On Restoration Of Mine Geological Environment Of Liaoning Lishugou Coal Mines

Ecological environment is the necessary condition of human survival andmine geological environment is the indispensable important component of theecological environment. Mineral resource which is an important pillar ofnational economy are the material basis of human survival and development.With the frequent mining activities, mine geological environment problemwhich is one of the most outstanding problem of ecological environment intoday’s society, causes varying degrees of influence to people’s lives andproperty, has seriously restricted the construction of ecological civilization. Sothe geological environment restoration of shut down mine is urgent needed.Lishugou coal mine is located in Saima town1km northwest, adjacent toresidents, and which coal resource is basically used up. The geologicalenvironment problems such as ground subsidence, ground collapse, Soilerosion, water environment destruction seriously threaten the local residents’life and production, the restoration of which is imminent. That is not onlynecessary, but also a very urgent task faced by the governments at all levels.Comprehensive analyzed the mine geology, mining, hydraulic loop, geologicaldisaster assessment data, field surveyed and analyzed mine geologicalenvironment problems, to combine with theory of vegetation ecology,landscape ecology, agriculture, forestry, economics and social sciences an soon, design a variety of the feasible recovery schemes. According to the actualsituation of the mining area and the characteristics of the geologicalenvironment, and comprehensive analysis on the advantages anddisadvantages of various options and time limit for a project, select the mostsuitable environmental recovery plan for this area. Then according to the plan,design various management restoration project technical requirements toachieve successful control of the mine area.The successful geological environmental restoration project of Lishugoucoal mine will improve the local ecological environment, reduce theoccurrence of geological hazards, and promote the construction of ecologicalcivilization in our country. It play a model leading role in the local minegeological environment restoration demonstration management work.Lishugou coal mine geological environment management recovery modebecome scientific reference for geological environmental recovery of theunderground mining of shallow coal mine in our country.Mining Environmental Restoration first occurred in Europe and the United States developed countries, China in the1960s. Currently from the mine“three wastes”(waste gas, waste water, waste residue) influence onatmospheric and water environment set out to research mine geologicalenvironment recovery. And focus on the "three wastes" discharge, Minegeological disasters such as collapse, landslide debris flows managementand abandoned open stope reclamation, etc. for which has got a lot ofachievements. The management of mine geological disasters such as groundsubsidence, ground subsidence, ground fissures, caused by goaf, andrecovery of agricultural cultivated land within the scope of governance goafsubsidence research are relatively weak.In this paper, according to the characters of the mine geologicalenvironment, put forward three kinds of treatment solutions for all sorts ofgeological environmental problems such as Surface collapse, groundsubsidence, ground fissure, waste and water pollution in mine area.①surfacebackfill and underground drilling grouting program.②surface backfill,underground backfilling and grouting drilling program.③combined surfaceand underground backfill all programs in three different treatment andrecovery programs. To systems Analysis geological background, geologicalenvironmental status and other information, think plan①, surface backfill andthe underground drilling grouting, is the most appropriate for Lishugou coalmine geological environment governance.This paper puts forward three kinds of coal mine geological environmentrecovery plans to governance the shallow underground goaf. And Put forwardthe concrete and feasible technical requirements for the various governancerestoration project. This is the main innovation of this paper, but also for othersimilar coal mines and other similar geological environment characteristics ofthe reference for the mine. According to this paper discusses the governanceof recovery program to restore the mine geological environment governance,can obtain good social benefit, environmental benefit and economic benefit,and fundamentally solve the problem of the mine geological environment.
