建井工程地质工作是加快建井速度、缩短建井工期、保证高质量建井的一个重要环节。由于缺乏必要的开发勘探资料和忽视建井地质工作等而造成矿井停建、工期拖延和资金大量浪费的事例很多,本文拟以甘肃省窑街、靖远两个矿区在建井工程中所发生的有关问题为例,列出问题的严重性,以便引起矿井工程建设部门的重视。 在窑街矿区,由于煤层位置判断不准,一号井—采区把两条长度均为600多米的运输斜巷,开凿在主要可采厚煤层内,结果,使300多名井下工人一年的工作,变成了无效 Well construction engineering geological work is to speed up the construction of wells, shortening the construction period, to ensure high-quality wells is an important part. There are many cases of stoppage of construction, delay of construction period and large amount of capital waste due to the lack of necessary exploration data and neglect of geologic work of well construction. This article intends to take place in the construction of two coal mines in Yaojie and Jingyuan, Gansu Province For example, the seriousness of the problem is listed in order to arouse the attention of mine construction department. In the Yaojie Mine Area, due to the inaccurate location of the coal seams, Well No.1 - the mining area carried two inclined transport lanes, each of which length was over 600 meters, excavated in the main recoverable thick seam, resulting in more than 300 underground workers for one year The work became invalid
