| Abstract: | Taking the long-distance holing-through project in the air-return alley of lower formation coal in San Jiaohe coal mine as an example, this paper introduces the scheme of holing-through survey and the error-predic-tion method. And tripod method in surveying of total station and gyro-theodolite orientation are adopted in the sur-veying, as well as the errors are predicted by Excel, which improves the holing-through quality and efficiency. And finally the accurate surveying is achieved. |
