The invention relates to a mining method for lead-zinc ore and the use of waste rocks. The mining method adopts open-pit mining, including the establishment of a reservoir, the opening of a working face, the setting of a cutting machine's guide rail, the installation of a cutting machine on the guide rail, the cutting and mining of ores, the on-site monitoring of the mined ores, screening, divided into ores and waste rocks respectively. Pile up until the ore is completely finished. The uses of waste stones include making sand and stone, and also for processing plates. The width and length of the working face of this method are not limited, and the mining depth can be fully mined. This method is not only suitable for new mines, but also suitable for old mines which have been mined but the ore has not been mined. It is a non-polluting, accident-free and resource-wasting mining method because of on-site monitoring, screening, sorting and stacking of the ores, avoiding waste stones from entering the processing procedure, and the cutting machine saw blades are cooled by water and the waste water is recycled. The selected refineries can also be put near mining points to save land. The waste rock obtained by this method is also fully applied.

铅锌矿的开采方法及其废石的用途
本专利技术涉及一种开采方法及其废石的用途，特别是一种铅锌矿的开采方法及其废石的用途。
技术介绍
目前，开采铅锌矿基本上都是采取矿井掘进，炸药爆破矿井的方法。由于矿井不是露天，而且空间有限，采矿时会产生空气、废水污染，工人会患上职业病（矽肺）。因为采用多层次开采，频繁进行钻孔、爆破，容易发生崩塌、透水等事故。同时矿脉深采用爆破推进受到限制，矿石无法完全采完，造成资源浪费。再有采用爆破采矿，没有条件测矿、选矿，只能将所采石头（包括废石）全部运去选矿区，增加费用。炸药爆破的矿石部分过大，且不是块状，现有的选厂都要大型破碎机破碎，经球磨机磨成浆状，输送到选矿池加药水，经提炼将铅锌分离出来。池里剩下的废渣和废水经管道送到固定地点堆放，堆满后重新征地作废料堆放场，占用场地较多。
技术实现思路
