煤矿井下巷道贯通测量误差预计及方案调整
|
摘要
贯通测量精度对最终巷道贯通工程效果有着重要的意义,会对矿井建设和生产造成影响,需制订有效的测量方案。结合矿井实际测量工程,对贯通测量误差进行了预计,提出了导线测量方案,对比分析了各个方案的可行性。工程实践证明,所选贯通测量方案大幅度提高了巷道贯通精度,且简便易行,有效缩减了工程贯通测量任务量。
Break through survey accuracy is of great significance to the effect of the final roadway break through project, which will affect the mine construction and production, and an effective measurement plan needs to be developed. Combined with the actual measurement engineering of the mine, this paper predicted the break through survey error, proposed the traverse measurement scheme, and compared and analyzed the feasibility of each scheme. The engineering practice proves that the selected break through survey scheme has greatly improved the tunneling penetration accuracy, and is simple and easy to implement, effectively reducing the amount of engineering break through survey tasks.
