摘要
目前,我国的小规模矿山数量占比达70%以上,其产能占比却不足45%。受经济下行的影响,矿山开采企业缺乏资金投入,导致其无法对现有的老旧设备与落后的生产工艺进行更新与升级。这些不利因素都极大地制约了我国绿色矿山建设工作的进行。
At present,the number of small-scale mines in China accounts for more than 70%,but its production capacity accounts for less than 45%.Affected by the economic downturn,mining enterprises lack capital investment,resulting in their inability to update and upgrade the existing old equipment and backward production technology.These unfavorable factors have greatly restricted the construction of green mines in China.
