基于GPS的兴隆庄煤矿的近井网建设与十字中线恢复

The Near Well Network Construction and Cross Center Line Recovery of Xinglongzhuang Coal Mine Based on GPS Technology

摘要:

兴隆庄煤矿近井网和井筒十字中线破坏严重，为了保障煤矿正常的生产需求，利用GPS技术建立了D级GPS近井网，利用三等水准测量确定了近井网各GPS点的正常高程，并利用高精度全站仪恢复了井筒十字中线，进行了垂直度检测，埋设了基桩点。

Abstract:

The near well network and the cross line in Xinglongzhuang coal mine have been destroyed seriously. In order to meet the normal production needs of the coal mine, D degree GPS near well network has been set up based on GPS technology, and normal elevation of GPS points in the near well network have been determined by using the third order leveling surveying. The cross line of the shaft center has been restored by using high precision total station, the vertical degree been detected, and the foundation pile points been buried as well.
