在一定时间内回采矿石的快慢程度。开采强度取决于采矿准备工作的连续性与进展速度，和同时进行回采矿块（或采区）数量的多少。一般用采矿强度和年下降速度这两种指标来表示矿山的开采强度。
地下水开采强度愈大，塌陷数量愈多。
The more intesive the development strength of groundwater, the more the amount of collapses is.
南四湖区煤炭资源丰富，开采强度较大；
There is rich coal resource in Nansihu area, and mining denseness is very large.
通过优化开采设计，把开采强度限制在煤矿区地质环境可以承受的范围之内。
The damage of ground environment should be limited to the acceptable degree based on the bearing capacity of geological environment by restricting coal mining.
