贯通测量误差预计参数的分析与确定

贯通测量误差预计多采用规程规定的测量参数,而规程参数多假设在比较理想的环境下,是经过相应理论推导的结果。但是由于各矿井的具体条件不同,在巷道贯通后分析巷道贯通误差,以现用规程规定的误差参数预计的误差与实际差别较大。因此,各矿要根据自己实际情况的不同,进行误差预计参数的确定。本文首先对贯通测量误差参数的类型和重要性进行了综合评述,并对其中地面控制网误差参数和井下控制网误差参数的理论确定方法进行了介绍,用实测资料进行确定。

The Analysis and Defining of Estimation Parameter of Through Survey Error

Estimation of through survey error usually adopt the parameter of the rules provision. But the parameter of the rules provision usually is difined under the ideal environment, and it is deduced by relevant theory. Because of the specific conditions of each mine are different, the error that it is difined by the rules provision is bigger than practical errror after analyzing the throuth survey errorr. Therefore, every mine determine the parameters of error according to their actual eonditions. This paper commentates the importance and type of the error parameters synthetically, and introduces the ac demie method to define the major error parameters （ground control net error parameters, underground control net error parameters）, and difining them with the actual data.
