在煤田地质勘探中,为取得煤质资料,常常专门布置坑道进行采样分析。目前一般多采用平硐掘进方式,不但通风排水便利,对于系统收集坑道水文地质资料也特别有利。坑道地质员除了进行一般的地质描述及采样编录外,尚需负责坑道水文地质原始资料收集工作,最终资料的汇总则由水文地质员担任。坑道地质员在描述岩性及制图的同时,应简略的记录其水文地质现象,一般可分为四种:1.干燥的地段(岩石表面无水);2.潮湿的地段(岩石表面有水,但无补给来源);3.滴水的地段(水由层面或裂隙呈不连续流出);涌水的地段(水由层面或裂隙连
In the coalfield geological exploration, in order to obtain the coal quality data, the tunnels are often specially arranged for sampling and analysis. At present, the general use of horizontal tunneling approach, not only the convenience of ventilation and drainage, for the collection of tunnel hydrological data is also particularly beneficial. In addition to carrying out general geological description and sampling cataloging, tunnel geologists still need to be responsible for the collection of raw materials of hydrogeology of tunnels, and the final data will be compiled by hydrogeologists. While describing the lithology and mapping, tunnel geologists should briefly record their hydrogeological phenomena and generally can be divided into four types: 1. dry area (rock surface is free of water); 2. wet area (rock surface has water , But no source of supply); 3. The area of the drip (water discontinuously flows out of the level or crevice); the area of the gushing water
