Study On The Ecological Reconstruction Technology Of A Rock Mine Slope Based On The Quality Division Of Rock Mass

Limestone as an important building and chemical material,its market demand is very huge,but the stone mining area formed by mining has caused serious damage to the ecological environment of the mining area and its surrounding areas.Therefore,the research on Ecological Restoration Technology of stone mining area is one of the effective means to build green mines.The ecological restoration project of stone mining area mainly includes rock slope,working platform,pit bottom,mining road,industrial square,waste dump and disturbed area around mining boundary.In the above-mentioned areas,the rock slope has become the key and difficult area for ecological restoration of stone and mineral areas due to the extremely poor site conditions.Therefore,it has important engineering application value to carry out the research on ecological restoration and reconstruction technology of rock slope in stone mining area.Taking the northern slope of a large limestone mine in northern Tangshan as the research object,based on the investigation of the natural geography,mining status and ecological damage within the mining area,the north slope is divided into different regions according to the basic information of slope rock quality,slope angle size,step height,slope rock weathering degree and structural plane development,According to the characteristics of each region,the corresponding ecological restoration technology was selected.The main research contents of this paper are as follows: using the method of field investigation,obtaining the basic information of mine geology,mining status and vegetation damage,combining with the basic information of slope angle size,bench height,slope rock weathering degree and structural plane development,the northern slope is preliminarily divided;on the basis of preliminary regional division,each area is dry The uniaxial compression mechanical experiment was carried out with water saturated rock to obtain the basic mechanical parameters such as uniaxial compressive strength.Combined with the basic information of rock mass discontinuities obtained by non-contact measurement,the strength parameters of rock mass in each region were calculated and the rock mass quality of each region was evaluated.Based on the evaluation results of rock mass mass mass,combined with the structural information of slope rock mass in each region,the gas in mining area was fully considered On the basis of climatic and soil conditions,according to the advantages and disadvantages of the existing ecological restoration technology of rock slope and the applicable conditions,the corresponding ecological restoration technology scheme is selected.Figure 24;Table 11;Reference 125...
