摘要
以锡铁山铅锌矿深部围岩为对象,基于水理性质试验方法,了解到其在水的作用下易发生软化、膨胀和崩解等现象,并对软岩多次吸失水后的变化情况进行了研究。试验结果表明,软岩多次吸失水,更容易发生软化、膨胀等现象。试验所找到的作用规律可以为该矿山的围岩稳定性研究提供依据。
Taking Xitieshan Pb-Zn Mine's deep surrounding rocks as research objects,based on the waterphysical property tests,it's learned that deep rocks are easy to soften,expand and disintegrate under the action of water.With studying the situation changes after the soft rock is repeatedly exposed to water absorption-dehydration processes,we found that soft rock is easy to soften and expand with the increasing of test time.The effect rules we found in the test can provide basis for studying the stability of surrounding rock of this mine.
