摘要
胶带机头联络斜巷主要承担顾桥矿井-665m水平至-780m水平的联络运输任务。斜长245m,倾角为29°,分上、下两段相向施工。由于顾桥矿井地质条件复杂,工程质量要求高,采用了严密误差预计,操作得当,措施合理,测角、高程测量准确,线量误差为52.4mm,保证了胶带机头联络斜巷的贯通精度。
The contacts steep tunnel of belt loader installation is mainly undertakes transport from-665m to -780m levels.inclined length 245m,angle 29°.the survey is divided into two sections（the upper section and the lower section）,owing to complicated geological condition in Guqiao mine,rigor error calculation in advance is adopted.Thanks to proper operation,reasonable measures, as well as accurate angle and height measuring,linear error is only 52,4mm,ensuring the holding through accuracy. Key Words：steep,transfixion survey, error predication
