    The brought results over of research of co-operation of boring working organs with soil at well-drilling by active dynamic working organs and the use of different elements destroying soil. A study of motion of particles of soil is undertaken on screw of boring worker of organs of dynamic action and a calculation chart over of motion of particle of soil is brought. As a result of analysis of existent researches and publications, a research aim is put, namely: analytical research the result of that will allow designing screw working organs with preset parameter to screw and by necessary office hours, minimizing the way of passing of particles of soil for them. These recommendations are from structural perfection, reduction to power-hungriness, increase of the productivity and economic efficiency of active dynamic working organs of boring machines.

    At the mining depths reached in the Karaganda coal basin (up to 830 m), it is impossible to achieve maintenance-free maintenance of workings using modern supports. This would require a support resistance of over 1.7 MN/m2, but modern supports have a resistance not exceeding 0.2 MN/m2. It is necessary to look for other ways to improve the condition of workings and save material resources.
