In the paper the Mobile Inclinometric Station for blastholes survey is presented. Working out purpose is securing of drilling accuracy in the technology of underground mass explosions. Many years this problem did not find the effective decision at the mining enterprises either of Russia, or abroad. The station is intended to perform inclinometric survey of group blastholes trajectories with a mutual binding of one group wellbores. Operation productivity was not less than 20 wellbores during a shift. The Station comprises the following equipment: a downhole tool (an autonomous gyroinclinometer) with centralizers, a ground device, a round-trip device with a depth sensor, and a device for relative geodesic positioning of well tops. The weight and device dimensions make it possible to use it in the excavations distant from a network power supply and transport communications. The results of the Station tests are also presented in the paper. Now the station is under the pre-production tests in Gubkin mine.
