摘要
煤矿井下贯通测量是煤矿测量工作中的一项关键工作,山西省中阳县荣欣焦化有限公司高家庄一矿主井与二矿主井贯通测量,对地面近井点采用全球定位系统GPS进行了测量、井下陀螺经纬仪定向,达到了测量工作各项技术规范,提出贯通测量的步骤和要求,通过测量结果精度分析,采取了保证精度的技术措施,使得此次贯通能够顺利实现。
The paper indicates the holing-through survey of coal mines are the key phase in the coal mine survey, adopts GPS to accomplish the survey at the ground near-shaft control point of the holing-through survey of the First and Second Main Coal Mines at Gaojiazhuang Village by Rongxin Coking and Chemical Co., Ltd in Zhongyang County of Shanxi Province, indicates the location of the theodolite under the mine to achieve various technical specifications of the survey, and points out the steps and requirements for the holing-through survey, and adopts the technical measures to ensure the accuracy by measuring the accuracy analysis, so as to realize the holing-through of the coal mine.
