1 Natural economic conditions and human environment
It is necessary to investigate the vegetation coverage of stone mine resource areas, the level of local economic and technological development, labor resources and levels, whether there are highways, railways, high-voltage lines passing near the resource areas, and whether there are important buildings such as residential houses and cultural relics in the vicinity of the resource areas. things and their disposal.
Whether the resource is located in animal, plant or natural resource reserves, etc., evaluate the possible impact of the mining of stone resources on the natural and human environment.
2 Soil and water conservation and restoration
Evaluate the impact of stone resource mining on groundwater and surface water bodies and the possible damage to the environment due to soil loss according to the resource situation, and evaluate the restoration and reclamation of natural landscapes after mine closure.
3 Geological Hazard Assessment
Fully evaluate the safety hazards caused by subsidence, collapse, ground cracks, landslides and debris flows to stopes, mine roads, etc. during the mining and construction of stone mine resources. The second is the potential harm caused by geological disasters to surrounding areas after mine closure.
economic benefits
Many evaluation factors of stone mine resources are ultimately aimed at achieving greater economic benefits with lower costs and inputs.
According to the actual situation of the stone mine resources to be developed, through in-depth and meticulous research, analysis and multi-plan comparison of various elements, according to the market price of stone varieties, determine the investment scale, calculate the production and operating costs, and estimate the sales revenue and profit. and cash flow factors.
Determining economic data on stone resources to evaluate return on investment and economic benefits.
In short, the comprehensive economic and technical evaluation of the development of stone mine resources must comprehensively examine various factors, carefully study the reserves, production and consumption trends of domestic and foreign stone resources and varieties, and the types, quantity, quality, price and proposed development of stone varieties. Conduct analysis, research and forecast on the competitiveness of stone products;
Carefully study the own characteristics of stone resources, and comprehensively consider the influence of geological, engineering, environmental and other factors; truly technically feasible, economically reasonable, environmental and other conditions permit, in order to correctly evaluate the economic and technological prospects of stone mine resource development, Make the development of stone mine resources stronger and better.
