The unified algorithm for geodetic notches on the plane was proposed. The idea of the algorithm is to introduce a local coordinate system and the form of the equations of position lines in a simpler form that can solve these equations by simple means. The formulas convert coordinates from one system to another. On the example of the reverse resection shows the potential of the proposed algorithm for the solution and assessing the accuracy of complex notches.

The paper presents the theoretical and measurement-determined mining ground subsidence after the termination of longwall mining. The changes involving the subsidence speeds of the observed points in time were defined. For the determination of model parameters, a new comprehensive method was applied, which allows to apply in the calculations the results of continuous measurements involving the subsidence of a single point, realized within a short time period. The analyses involving the changes of subsidence and the changes of subsidence speed of the selected observed points have shown that the fundamental part of the influences is displayed on the surface ground almost immediately. The increase of subsidence after the stoppage of longwall front is insignificant and is displayed relatively fast. The bulk part of these subsidences is displayed during the preparatory mining works involving the liquidation of longwall timbering. In the presented example, after about six months from the stoppage of longwall front, the subsidence practically stopped its progress entirely. The obtained results have a relevant practical impact when estimating the value of subsidence increase, subsidence speed and the duration of subsidence after the termination of longwall advance. The estimation of these values can be carried out in accordance with the algorithm presented in the paper.

The analysis of existing approaches for justification list of base-parameters used to assess the geodynamic state territories was performed. two aspects of the term condition was considered. It was proposed to use qualimetrical approach to create the system of parameters to evaluate the territory geodynamic state. A parameters-tree and the base-parameters system were constructed. There were presented the values of the base-parameters, and provides references to the literature. An assessment procedure of the territories geodynamic state has been developed.

** A. A. Omelchenko. **Methods to predict doses of ionizing radiation at the stage of open pit or mine design for working rare-earth deposits with ore minerals of increased radiation (a case study of the Azov rare-earth deposit of the Priazovie) – p.47

Methods to predict doses of ionizing radiation and degree of radiation hazard of rare-earth ore minerals of increased radiation at the stage of open pit or mine design are first described. The essence of the methods is as follows. Firstly electronic 3D multifunction model of the rare-earth deposit is generated and areas of increased radiation, based on the large number of exploratory wells, are delineated. Then volumes of metalliferous deposits and radioactive zones at the given levels of increased radiation are calculated along geological survey lines for ore minerals of increased radiation and for the deposit in general. From these calculations equivalent doses in mine workings with the prevailing increased and top levels of radiation are calculated. Development of measures for environmental safety will be specified by the doses of ionizing radiation.
