在开采有用矿物时,人们历来希望尽可能有效地提高回收率。在开采技术高度发展的现阶段来看,这不仅受经济方面,而且也受生态方面的影响。图1和图2所示由采矿造成的对环境的不良影响,所导致的后果,反馈到企业生产上,比设计方法的影响更强烈一些。从图1和图2所示的情况,可以想像,这一类形不仅仅是在地表上产生有害影响。离工作面越近,这种变形将越大。这一例子说明,距地表很浅的工作面上方的变形和冒落过程,然而即使在较深的工作面回采,也产生类似的现象。 When mining useful minerals, people have always wanted to increase recovery as efficiently as possible. At this stage of the development of mining technology, this is not only economically but also ecologically influenced. The adverse effects on the environment caused by mining as shown in Figure 1 and Figure 2, the consequences of which are fed back into the production of enterprises, have a stronger impact than the design method. From the situation shown in Figure 1 and Figure 2, it is conceivable that this type of profile does more than just have detrimental effects on the surface. The closer you are to the work surface, the greater the deformation. This example illustrates the deformation and caving process above the working surface that is shallow from the surface, but a similar phenomenon occurs even when working on deeper working surfaces.
