本文主要就我们在铜、铅锌、铁、金、钨、锡、汞、多金属等15个不同类型矿床上进行的试验和试验性生产工作,阐明壤中气汞量测量的影响因素及其找矿意义.工作方法我们进行壤中气汞量测量的基本过程是:沿测线以10～40米(主要以20米点距)采样,但也试用过沿不规则路线采样.在测点的覆盖层上,用钢钎或手钻打成半米深的浅孔,把与金丝管、抽气筒(或大气采样器)连接的取样器置入孔中,使其与孔壁间封闭良好;然后根据测区壤中汞气的背景浓度等
In this paper, we mainly carry out the pilot and pilot production work on 15 different types of deposits of copper, lead, zinc, iron, gold, tungsten, tin, mercury and polymetallic and clarify the influencing factors Prospecting Methods of Work The basic process by which we measure the amount of mercury in the soil is to sample along the survey line at 10 to 40 meters (mainly at a pitch of 20 meters) but also to sample along an irregular path Cover with a drill or hand drill into a shallow hole half a meter deep, the gold tube, pumping tube (or atmospheric sampler) connected to the sample into the hole, so that the hole between the wall closed Good; then according to the measured background soil mercury concentration and so on
