堆积型铝土矿采场土壤对雨季采矿的影响研究

The Influences the Stope Soil on the Mining Activity During Rains in a Accumulational Bauxite Mine

堆积型铝土矿床开采工作面大,雨季采场土壤的性质对生产影响严重。根据试验及现场测试获得的采场土壤物理力学性质及其在雨季的变化情况,着重分析了采场土壤经雨水浸泡后其物理力学性质的变化机理和雨季对采矿运输设备运行及采场作业的影响,提出了针对雨季采矿的相应对策。

As the mining face of a certain accumulational bauxite deposit is large, the property of the stope soil has great influences on the mining activity during rains. Based on the physicomechanical property of the stope solid and its changes in rains obtained from the tests and the site measurements, this paper places emphasis upon the analyses of the changing mechanism of the physicomechanical property of the stope soil immersed by rain, and of the influences of rains on the operations of mine hauling equipments and the mining activity, puts forward some strategies for the mining in rains.
