本文针对大同矿区云冈矿坚硬顶板和坚硬煤层的特殊情况，以及测绘工作的不足，分析了当前煤矿测绘工作存在的主要薄弱环节，并提出了针对性的强化措施。将 CGIS 数字化测量技术运用到煤矿测绘中，通过rnCGIS 数字化测量技术与传统测绘技术分析研究对比，数字化测绘技术精度明显更高，对煤矿后期的开采质量有了更有利的支撑。“,”in view of the special situation of hard roof and hard coal seam in Yungang Mine of Datong mining area, as well as the shortage of Surveying and mapping work, this paper analyzes the main weak links existing in the current coal mine surveying and mapping work, and puts forward the corresponding strengthening measures. CGIs digital measurement technology is applied to coal mine surveying and mapping. Through the analysis and comparison between CGIs digital measurement technology and traditional surveying and mapping technology, the accuracy of digital surveying and mapping technology is significantly higher, which has a more favorable support for the later mining quality of coal mine.
