The coal measures strata mostly form and reduce the environment, is in the environment of oxidizing after the coal seam is exploited, it flow iron ore after being with keeping in touch well water and air ore,oxidize one that is a series of, hydrolysis,etc. react, make water present acidity, form the acid ore well water. Cause certain environmental impact and destruction to groundwater, other environments and facility,etc.. This text to acid ore danger of well water, reason of forming and well water prevent from and administration go on simple exposition to acid ore.Key word: Activity of mining Acid ore well water Environmental impact Prevent AdministrationThe coal is the main energy of our country, accounts for more than 76% in the disposable energy in our country, must carry on a large amount of coal mining. Mine course destroy environment that coal seam in, make reducing environment bee the environment of oxidizing original its. Generally all contain about % 5% sulphur in the coals, exist in the form of pyrite mainly, account for coal 2/3 containing sulphur quantity. Coal seam in environment of oxidizing exploit, flow iron ore with after ore keep in touch by well water and air, react a series of oxidize, hydrolysis,etc., produce sulfuric acid and hydrogen oxidize irons, make water appear acidly, has produced the acid ore well water. The ore well water that pH is lower than 6 calls the acid ore well water. Acid ore well water some colliery make southern colliery part paratively extensive especially in our country. Of our country southern ore well water pH of colliery generally until , up to sometimes. It has close relations that high in sulphur in reason and coal why pH is low. The forming of the acid ore well water causes serious pollution to the groundwater, will also corrode the apparatus and concrete borehole wall in the pit such as the pipeline, water pump, rail at the same time, pollute the surface water and soil seriously too, make the fishes and shrimps in the river peerless, the soil board is formed, the crops are withered, influence the health.1 Danger of an acid ore well waterPH of the ore well water is lower than 6 acidly, have certain corrosivity to the metal apparatus。 PH lower than, 4 have stronger corrosivity promptly, shut to safety in production ecological environment of mining area produce and endanger seriously. There is the following several respect specifically:1) Corrode transporting equipment of colliery such as the rail, steel wire rope in the pit. Rail, pH 4 acid ore well water corrode, intensity will reduce greatly to dozens of day more than ten day steel wire rope, can cause the incident of transporting.2) Visit and put low always empty water of pH, the iron accuses of water pipeline and gate to corrode quickly under the circumstances that the rivers is eroded.3) SO2 content is very high in the acid ore well water, interact and produce moisture sulphate to form with some positions in cement brilliant. The volume expansion while turning into of salt. Through determining, when SO4 produces CaSO42H2O, the volume increases one time。 While forming MgSO47H2O, the volume increases 430% of the concrete structures structure.4) The acid ore well water is still the environmental pollution sources. The acid ore well water enters the river, pH quality is smaller than 4 o39。clock, will enable fish39。s death。 The acid ore well water enters the soil, destroy the granule structure of the soil, make the soil board form, the crops are withered and yellow, the output is reduced, influence the relation between workers and peasants。 The well water mankind of acid ore is unable to drink, keep in touch for a long time, can make the tricks of people break, eyes importance, enter the human body through the food chain, influence the health2 Reason why the acid ore well water formsCoal measures stratum form on environment of reducing mostly, containing pyrite (FeS2) coal seam form on better to reduce the environment. Generally all contain about % 5% sulphur in the coals, exist in the form of pyrite mainly, account for coal 2/3 containing sulphur quantity. Coal seam in environment of oxidizing exploit, flow iron ore with after ore keep in touch by well water and air, react a series of oxidize, hydrolysis,etc., produce sulfuric acid and hydrogen oxidize irons, make water appear acidly, has produced the acid ore well water. The main chemical reaction that the main reason why the acid ore well water forms takes place promptly is as follows:1) The pyrite oxidizes and produces free sulfuric acid and inferior iron of sulfuric acid：2FeS2＋7O2+2H2O2H2SO4+2FeSO42) Sulfuric acid inferior iron turn into the sulfuric acid iron under free function of oxygen： 4FeSO4＋2H2SO4＋O22Fe2（SO4）3＋2H2O3) In the ore well water, the oxidation of the inferior iron of sulfuric acid, might not need sulfuric acid either sometimes： 12FeS2＋3O2+6H2O4Fe2（SO4）3＋4Fe（OH）34) The sulfuric acid iron, further dissolve the function of different mineral of sulfides in the ore well water：Fe2（SO4）3＋MS＋H2O＋3/2 O2M SO4+2FeSO4＋H2SO5) Sulfuric acid iron hydrolyzed but free sulfuric acid emerges among the weak acid water： Fe2（SO4）3+6H2O2 Fe（OH）3＋3H2SO46) When the deep department hydrogen content sulfide of the mine is high, under reducing the condition, the ore well water rich in inferior iron of sulfuric acid can also produce free sulfuric acid：2FeSO4＋5H2S2 FeS2＋3S
