由于采矿企业改为经济核算和自筹资金,对这些企业来说,获得用于发展科技进步的自有资金意义尤为重大。在此情况下,企业愈来愈关心改造和技术更新中迅速取得实际收益的问题。可选择能最好地体现科技进步成果的方案来评价改造的得失。按每一方案(考虑到动态情况)来确定费用和效果。成果评估的价值超过用于改造的资源总费用的部分,即为改造的经济效益。迄今为止,整体准则被认为是确定在采矿工业条件下的费用较为流行的一种方法,
Owing to the change of mining enterprises to economic accounting and self-financing, it is particularly significant for these enterprises to obtain their own funds for the development of science and technology. Under such circumstances, enterprises are increasingly concerned about the prompt realization of real gains in reconstruction and technological upgrading. Alternatives can best reflect the results of scientific and technological progress programs to assess the gains and losses. Per program (taking into account the dynamic situation) to determine the cost and effectiveness. The value of the result evaluation exceeds the total cost of resources for transformation, which is the economic benefit of the renovation. To date, the overall guidelines have been identified as a more prevalent method of determining costs in the mining industry,
