河北某矿区蚀变围岩力学特性

Mechanics Nature of Altered Host Rock of an Ore District in Hebei Province

河北某矿区围岩为蚀变岩 ,遇风、水强度显著降低且有风化水解现象 ,严重影响了生产和安全 .本研究针对矿区的主要蚀变围岩进行了力学指标测试 ,并用模拟现场环境的方法试验研究了风化对岩石物理力学性质的影响 。

The host rock of an ore district in Hebei Province is altered rock,it has the character of weathering hydrolysis and its strength will be impaired when it suffered from wind & water,which influences the production and safety seriously.The mechanics index of major altered host rock is measured and the influence of weathering on the rock mechanics nature is studied by simulating on the spot surroundings.The testing result can help the mine to produce safely.
