摘要
和田玉是在一定温压条件下,由镁质大理岩与中酸性岩浆岩发生热液接触交代作用而形成的一种高价值矿床。随着市场的需求量越来越大,更多的和田玉矿床将被开采。根据笔者在矿区的水工环工作实测,该矿床可采用露天或者坑采方式开矿,因此对矿区的工程地质和水文地质条件要求较高。同时借鉴同类矿床开采经验及矿区实际,采用人工分拣、汽车运输、低品质就近处理、高质量深层加工的方式可最大限度的节约成本,提高产品价值。
Hetian jade is a kind of high-value deposit formed by metasomatism of metasomatic marble and middle-acid magmatic rocks under certain temperature and pressure conditions. As the demand for the market grows, more and nephrite deposits will he mined. According to the author in the mining area of the work of the hydraulic ring measured, the deposit can be used open-pit mining or pit mining, so the mining area of engineering geology and hydrogeological conditions require a higher. At the same time learn from the experience of similar deposits and mining practice, the use of artificial sorting, motor transport, near the low-quality treatment, high-quality deep-processing approach to maximize cost savings and improve product value.
