In this XinZhou kiln ore central air return the breakthrough of the two Wells up the mountain project breakthrough measurement. In this paper, firstly summarizes the general situation, link up the mine in order to find the material utilization, Second tells in coal mine roadway expedite can be used in the breakthrough scheme. According to the characteristics of the breakthrough to select the best breakthrough scheme, measurement methods, and measuring tool, And then based on the scheme, methods, tools to scheme is expected to be the error, Through the calculation of the error determinate, calculating the expected error , Here is only expected to error, and not real measurement errors . Calculated error is expected to again with the roadway expedite allow error comparison, see if overrun or not. The last of the data accu
