Abstract.
The first time received results by mining and experimental work on the prevention of sudden coal and gas by the hydrodynamic impact on connivent coal seams k3– «Derezovka», k3v – «Derezovka-upper» and k3n – «Derezovka-bottom», before they are crossing crosscut. Crosscut crosses the seam at an angle of 50˚ with a further decrease the angle of approach up to call in on the seam k3n – «Derezovka-bottom». This fact and the small distance between the seams k3-«Derezovka» and k3v– «Derezovka-upper» (1,7 m) and k3v – «Derezovka-upper» and k3n – «Derezovka-bottom» (4.3 m) resulted in the need to develop a scheme emplacement of technological holes, which providing unloading seams. Hydrodynamic impact of the coal massif produced by of technological holes drilled from the workface of the crosscut in the block. The parameters of the hydrodynamic effects on the coal seams before they crossing with the implementation the criteria of effectiveness were set.
Keywords:
coal massif, sudden coal, located near coal seams, hydrodynamic impact, technological holes.
