mining recovery rate的意思|示意

A high or low coal recovery rate of the top coal caving mining is related to the key technology of the coal mining method to be widely applied.

放顶煤开采煤炭回收率的高低是关系到能否推广这种采煤方法的关键技术。

In addition, protection planning, in accordance with its characteristics, to guide the total, comprehensive utilization of associated minerals and mining recovery rate, recovery improved.

除此之外，在保护规划中根据其特点，指导其共(伴)生矿产的综合利用以及采矿回采率、采收率的提高。

Microseismic monitoring technique is of important meaning for the safety of coal mine, the prediction of the period of mining pressure and the increase of recovery rate.

微地震监测技术对确定采场覆岩“两带”高度、预报采场顶板破坏、预测煤与瓦斯突出，从而预防灾害发生、保证煤矿安全生产并提高资源回采率等具有重要意义。

This paper analyzes the preconditions for small and medium-sized coal mines to increase coal recovery rate, and puts forward some paths and measures for the second mining of the coal resources.

分析了中小煤矿提高煤炭资源回收率的前提保障条件，提出了复采煤炭资源的途径和措施。

The greater mining height mining is higher in resource recovery rate, better in coal quality, high in output and efficiency and good economic benefit.

大采高开采资源回收率高，煤炭质量好，能实现高产高效，经济效益好。

The challenge, says Duke’s Van Dover, “is to ensure that cumulative effects of mining activities do not exceed the rate of recovery of the organisms that rely on these habitats for survival.”

杜克大学的范多佛说，真正的挑战在于，“必须确保开采活动所积累的影响不会超过那些在该区域栖息的生物再生的速度。”
