摘要
根据冬瓜山井巷掘进期间记录到的岩爆资料;;总结了该矿井巷的岩爆特征和发生条件。对该矿床几种主要的岩石进行了强度试验、峰值强度前的加卸载试验、全应力应变试验和峰值强度后的松弛试验;;指出该矿床矿岩除大理岩外;;其他岩石都具有不同程度的岩爆倾向性;;提出了岩爆具有本源性和诱导性两种属性的观点。
The characteristics and occurring factors of the rock burst occurred in the development workings are summarized on the basis of data recorded during of the drifting of the development workings at Dongguashan Mine. Many experiments were done using these rock samples of the mine in laboratory, which included tension tests?total stress strain tests?tests of cyclic load unload before peak strength and tests of stress relaxation after peak strength. In the light of the results of these tests, it was found that all the other rocks in the deposit have a tendency to rock burst, except marble. The viewpoint was proposed that rock burst has two properties of self source and inductivity.
