Study Of Geological Environment Protection In Ming Ye Mine

One of the most important negative effects in the development of mineral resources is the destruction of the mine geological environment,which has gradually become an important factor affecting the normal production of the mine and the safety of the living environment of the living environment,and gradually accumulated and evolved into a key problem that hinders the health and sustainable development of the mineral industry in China.Taking Ming Ye coal mine as an example,this paper evaluates the present situation of geological environment and predicts the possible geological environment influence in the process of future mine development.Finally,the corresponding protection and restoration measures are put forward according to the specific situation of Ming Ye coal mine and the prediction results of the previous article.After coal mining,according to the geological conditions and mining conditions of the mining area,the influence degree of the geological environment of the mine is determined to be"serious"and"lighter"two levels,with the area of 7.3113km~2 and1.1654km~2 respectively.The mining activities are divided into three grades of"serious","serious"and"lighter",with an area of 0,4151km~2,6.2036km~2 and1.8580km~2,respectively.The impact of mining activities on land resources is divided into two levels,"serious"and"lighter",with an area of 6.5217km~2 and 1.9550km~2,respectively.Under the present conditions,the collapse,landslide and debris flow are not developed,and the ground cracks are induced by coal mining.The main threat is woodland and other grasslands,which are less dangerous and less dangerous.There are 2 unstable slopes in the industrial site.There are 2 unstable slopes in the outcrop failure area of the coal seam.The current situation is in the unstable state and the influence degree of the geological disaster is"lighter".The influence degree of coal mining activities on the aquifers is"serious",and the influence degree of other unexploited areas to the water bearing layer is"relatively light".The construction of the industrial site and the wind well site,the destruction area at the outcrop of the coal seam,the waste residue stacking on the original topography and landform landscape,the degree of damage to the topography and landforms is"serious",and the influence degree of the land resources in other areas is"light".The restoration and treatment of mine geological environment includes industrial site unstable slope protection,waste rock field,industrial site setting off drainage ditch,land collapse,fissure landfill,industrial site planting,and centralized water supply for three villages affected by mining.The monitoring measures include ground cracks,monitoring of ground subsidence,deformation monitoring of building facilities,deformation monitoring of landslides,landslides,monitoring of debris flow and gully,monitoring of groundwater and so on.
