钻探注浆充填技术在矿山生产中的应用

Application of drilling grouting filling technology in mine production

在我国矿山生产中,大多都需要露天的开采场地、矿井与坑口等,但是由于地下矿层的大量开采,就会产生一定的地下空间,这类空间就被人们称之为采空区,而采空区由于缺乏相应的稳定性会出现位移、垮塌,导致地表上层的开采场地出现弯曲,损坏变形的现象。相关的企业因为专业技术的限制无法对这些采空区面临的安全风险进行处理,最终造成不同程度的地质灾害发生,甚至会出现坍塌的现象。所以如何采用有效的技术,对矿山中存在的问题进行处理,就成为相关从业人员需要研究的重要问题。

In China＇s mine production, most of the open-pit mining sites, mines and pit openings are required, but due to the large number of underground mining, there will be a certain amount of underground space, this kind of space is known as goaf, and the goaf due to lack of corresponding stability will appear displacement, collapse, resulting in ground. The upper level mining site is bent and damaged. Because of the limitation of professional technology, the related enterprises can not deal with the safety risks faced by these goafs, resulting in different degrees of geological disasters, or even collapse. Therefore,how to use effective technology to deal with the problems existing in the mine has become an important issue for the relevant practitioners to study.
