Abstract: This calculation system’s development design is based on the thinking of the software flow, it primarily make use of the software flow for data of conversion and deliver. It can match to analyze t many point data of survey, and the transform calculation in the general terms, mountain area the ground transform calculation, the calculation of strap mining ground transform, it is also software system for the calculation of stay and mine width of strap mining in computer screen. According to the mining geology term, it can be used for anticipating displace transform on the main cross, and the basin’s alignment with (or) incline to the ambulation of the main cross section with transform to distribute along the sink bottom, and arbitrarily point of the mine influence displace transform value.
