根据煤矿基建单位测量人员少,仪器少的实情,探求一种简便的两井定向方法,从理论上证明此方法的可靠性,再用实例证明对基建单位有一定的使用价值。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有这两种条件,在建井期间一般的大、中型矿井几乎都要进行两井间的贯通测量工作。那么,如何在人员少、仪器少的情况下,获得高精度的测量成果就是本文所探讨的方法。
According to the fact that there are few surveyors in coalfield infrastructure units and few instruments, a simple and convenient orientation method of two wells is explored, which proves the reliability of this method theoretically. And then it is proved by examples that it has certain value to the infrastructural units. Well orientation than two wells with a high precision, occupy the advantages of wellbore less time. But it requires two sets of equipment (theodolite, steel ruler, etc.), two groups of personnel, up and down at the same time homework. At present, most of the infrastructural units do not have these two conditions. During the period of well construction, almost all of the large and medium-sized mines need to carry out through-hole surveying between the two wells. So, how to obtain high-precision measurement results with fewer personnel and fewer instruments is the method discussed in this article.
