摘要
巷道贯通是煤矿生产活动中常见的工程,贯通的准确性直接影响着煤矿井下的采掘工作。为了提高贯通测量的准确性,将全站仪和GPS测量这两种贯通测量方法进行比较,根据不同环境需求选择合理的测量方案,通过技术手段减少系统累积误差,才能保证贯通工程达到规定要求。
Roadway penetration was a common project in coal mine production, the accuracy of penetration directly affected mining work in underground coal mine. In order to improve accuracy of breakthrough survey, two measurement methods of total station and GPS measurement were adopted and contrasted, reasonable measurement schemes were chosen according to needs of different environment. System error was reduced through technical means to ensure connection project meeting specified requirements.
