摘　　要：当矿区有两个立井,且两井之间在定向水平上有巷道相通并能进行测量时,就要采用两井定向,两井定向较之一井定向有着精度高,占用井筒时间少的优点,但它需要两套设备(经纬仪、钢尺等)、两组人员,井上下同时作业。目前大多数基建单位不具备这两种条件,花园煤矿就采用了一种简便方法在人员少、仪器少的情况下完成了两井定向工作。When the mining area has two shaft, which are connected by roadway in the directional level and can bemeasured, we must use the two - shaft orientation, two - shaft orientation has high precision, and less time in occupyingthe well compared with one shaft orientation, but it needs two sets of equipment （ theodolite, steel etc. ）, two groups ofresearchers, working at the same time in underground. At present, most of the construction units do not have these twoconditions, huayuan coal mine used a simple method under little personnel, instrument completed two - shaft orientationwork.
