侯庄矿水平斜井反掘贯通测量误差预计

Error Prediction of Inclined Shaft Anti-de-sac Run-through in Houzhuang Mine

为满足生产需求,对侯庄矿-425～-340m水平新矿石井进行改造。通过选择斜井反掘贯通测量的方法,并进行误差预计,得出贯通重要方向误差为0.09956m,满足了国标要求的精度规范;同时为了更好地保证贯通,应尽量进行多次独立测量。

In order to satisfy the yield demand,the ore well alteration was made to Houzhuang Mine between level -425--340 m. By the solution selection for the run-through measurement of the inclined shaft anti-de-sac and error prediction obtaining that the important direction run-through error was 0.099 56 m,so achieved the precision requirements range of the country,meantime in order to better ensure that run-through,a multi-independent measurement should be carried out necessarily.
