大型地质灾害对地质矿产找矿工程施工的影响

Influence of large-scale geological disasters on geological and mineral prospecting engineering construction

大型地质灾害对地质矿产找矿工程施工的影响主要分为三个方面,分别为:由于大型地质灾害引发地质矿产找矿工程施工地面塌陷,对地质矿产找矿工程施工隧道部分结构带来的不利影响;由于大型地质灾害造成地质矿产找矿工程施工土体自然下沉,阻滞了其周围土体的沉降,隧道变形滞后于土体的沉降速度,隧道底部会产生一定程度的脱空,土压力降低;由于大型地质灾害降低地质矿产找矿工程施工安全性,其中,大型崩塌以及大型崩塌甚至会造成不可逆的影响。

The impact of large-scale geological disasters on the construction of geological and mineral prospecting engineering is mainly divided into three aspects:the ground collapse caused by large-scale geological disasters,which has adverse effects on the construction tunnel structure of geological and mineral prospecting engineering;the natural subsidence of soil mass caused by large-scale geological disasters,blocking its surrounding areas The settlement of soil,tunnel deformation lags behind the settlement speed of soil,the tunnel bottom will produce a certain degree of void,the earth pressure will be reduced;due to the large geological disasters reduce the safety of geological and mineral prospecting engineering construction,large-scale collapse and large-scale collapse will even cause irreversible impact.
