1. The date on mine workings construction by means of blast drilling technology in mines of Ukraine Minugleprom are shown/. A new curved and stop shape of the face is proposed. The results of its laboratory research are described. The opportunity to apply non-explosive expending mixtures for destroying a stop part of a face is analyzed. The results of practical introducing are given and further research outlines are marked.

2. The analysis of the technological state of mine workings at mines of Ukraine shows that blast - based drilling technology remains the basic one in long-term prospects. It can be proved with the recent statistical data. E. g. in 2008 in National coal mines they installed 445.6km of curved and preparatory workings, the half of general volume of construction being performed by means of blast - based drilling technology for setting mine workings by developing non - traditional solutions, which can compensate economic expenses. One of the technological factors which influence the production induce is the face shape. When applying the conventional shape the tension caused by the shape of roof and face joining are concentrated in the upper past working It can result in a probable rock collapse. Thus it is necessary to develop the face shape whir is able to minimize possible collapses in pre - fan part of the working. Besides, the fan shape has to favor cawing down on repair amount in the working where construction, which are worn caused by lumps of supporfiry rock, screwing of pipes and cables. It can be done by controlling the distance of rock scattering. Thus the development of new face shapes is a, up-to-date practical problem.

3. The review of the latest research and publications shows that little attention is paid to the impart of a face stope on technical in dice of preparatory mining work. The system problem of the roof slape influence on a permanent working maintained is dealt in parts 3 and 4. The types of supporting of a plane and curried roof shapes are shown and the technology of a temporary on permanent supporting is analyzed. The dependence of rock shifting on the angle of working crossing is indicated. However, the inflame of the face shape on working hours of working cycle isn't regarded.

4. The aim of this thesis is to cut down on duration and working hours of mine workings construction by means of increasing of rock collapse and decreasing of the thesis is to make the face curved and stope shaped, which leads to rock collapse creation of vomit are made possible by compact rock occurrence under the fan.

5. To indicate the trajectory of rock scattering the vertical target is set up made of cross-section paper which is stuck on a wooden frame with legs flat are developed in to the scuds of a blasting chamber. The holes, made in this target of broken rock made it possible to indicate the trajectory of its scattering. Then the series of blasts were performed with further measuring the distance and of rock scattering. Forever the distance of its scattering was measured from face and the stope face the type of a model after blasting the blast holes in the stope part of the face is shown on the Draining 1.

6. The shape of the face proposed was applied when developing "INSTRUCTION………" at the mine "Russia", " Selidovugol" and is introduced when constructing of the 3th southern drift of the seam L-1 wile the steep crosscut L-2 of the seam L-1 - L-2 at this mine with the help of blast works. Further research is at indicating the influence of NRS on the destruction of the face part of the proposed shape.
