The article presents a structural scheme for solving the problem of creating a highly effective technology for conducting and supporting preparatory workings, consisting in establishing the laws governing the development of geo mechanical processes for the development of rational technological schemes for conducting mine workings with anchorage. The order of development of technological schemes of carrying out of mine workings with application of an anchor fastening taking into account the intense condition of a file of rocks is generated.

The article describes the causes of occurrence and forms of geomechanical processes manifestation in surrounding coal-rock massif of mine workings supported by anchor support. Based on long-term field observations, six forms of typical deformations of the surrounding massif have been established. Design solutions to strengthen the anchor support or complete reinforcement of damaged sections of mine workings during geomechanical processes of local felling have been developed. They include: installation scheme, substantiation of parameters and list of used reinforcement elements; technology of work, a list of equipment used.

The peculiarities of technological processes of formation of submicron Schottky field transistors usingarsenide-gallium technology, i.e. the technology of Schottky field transistors formation with a self-alifned gate onthe basis of nitride or silicide of tungsten, are considered in the paper. A highly effective technology for theformation of capsular layers of AlN and BN nitride films by high-frequency magnetron sputtering of the propertarget in nitric plasma for the realization of GaAs-based MOS-transistors is developed.

The paper describes a proposal of rock burst control measures for excavation and mining of the area the Coalface No. 1 4064, which is located in the 1st mining block of the Mining Plant 1, locality Karviná. It is an area that has been left in place as a protective area for safety reasons due to the high risk of rock bursts, and it is bordered on both sides by old workings.The aim of the proposal is to extract the retained area by using rock burst control measures to reduce this risk. As a measure, extensive disintegration of the rock massif in the overlying rocks of the seam by blasting works was chosen, both in driving mine workings and in mining of the coalface.The article describes the methods and scope of implementation of active and passive rock burst control measures in standard situations and in the case of detection of an unfavourable stress level.
