Arrangement for determination of the continuity of thickness and of structural-tectonic elements of mineable layers, particularly of coal seams

Claim 1

Arrangement for determination of the continuity of thickness and of structural-tectonic elements of mineable layers, particularly of coal seams, having a reduced elasticity with respect to surrounding rocks, forming their rock cover and bedrock, providing a multicomponent blast base directionally orientated, composed of charges arranged along a line forming an angle of 45* to 135* with respect to the direction of the main beams of a transverse seam wave, a fuse for discharge of said charges, a generator of oscillations, a registration base composed of a number of seismic pick-up devices, said seismic pick-up devices arranged at the edge of a free surface, created by partial interruption of the coal seam by a mine gallery, a seismic amplifier having a number of inputs and at least one output, a registration device, a time standard, a DC voltage source for the seismic amplifier and a supply source for energizing the registration device and the time standard, the generator of oscillations connected to the fuse for discharge of the charges, the generator of oscillations connected to a first input of the seismic amplifier, to a second input of the seismic amplifier the DC voltage source being connected, other inputs of the seismic amplifier connected to groups of seismic pick-up devices, the output of the seismic amplifier connected to the registration device, which in turn is connected to the time standard, both being energized from the supply source.
