Abstract.Executes of shaking explosion at the mine workings on the coal mines of Ukraine is regulated by a number of specification documents. At the same time, when the im-plementation of shaking explosion holds many technological violations of condition and the gas-dynamic phenomenas often occur, including with human victims. The mode of shaking explosion is used in mines with a very wide geological conditions.

To specific outburst seams under executes of shaking explosion are recommended ways to re-duce the intensity and frequency of emissions of coal and gas. For this purpose methods of increasing the depth of area discharge of the bottomhole zone of the coal seam, which is achieved in the mine conditions through the use of advanced methods of loosening the host rocks, outstrip blasting, to explosives blast-hole charges in the host rocks, out-strip loosening (camouflet еxplosives) of coal array. In addition, the passport of blasting with form-ing of bulk block jumper are used. Increasing the area of unloading of bottomhole segment of coal seam formation is achieved by using outrunning torpedo of coal array or host rocks and outrunning gidroexplosion. As stated, the use of the regime shaking explosion during mining operations is one of the safest ways to deal with gas-dynamic phenomena, but at the same time it is usually one of the most eco-nomically costly, especially when the need for smooth operation of the coal mine, so the main areas of research should be continue in the direction of reducing costs and improving the efficiency of the process.

Keywords: mode, shaking explosion, use, conducting mine working, gas-dynamic phenomena, forecast.
