【 摘 要 】

The article deals with issues of creation of high precision mine surveying networks. They can be used for the building and equipment installation. Also there is a method of joint adjustment of satellite, geodetic and mine surveying measurements.. To solve this problem, we propose a mathematical apparatus for converting measurements into a local rectangular coordinate system. The joint system of linear equations of satellite and geodetic measurements is solved by the method of least squares by the method of conjugate gradients in a special software package. The complex has the ability to strictly precomputation the accuracy of mixed networks, taking into account all the geometric conditions that arise in the network. The articles shows the design technique of mine surveying base network for cable-belt conveyor, its precision estimation depending on methods and equipments for geodetic measurements.
