Abstract: FIELD: mining methods. SUBSTANCE: method comprises steps of providing in front of a stope behind a zone of a supporting pressure along a ventilation drift, adjacent to a worked out excavated column, in rocks of soil a saturation zone, and forming along a width and a length of that zone at its boundary with a coal seam a softening layer of a predetermined depth by drilling saturation holes until an upper boundary of propagation of pressure cracking and casing them near an upper boundary of the saturation zone; making the above mentioned softening layer by high pressure moistening, being performed after coal seam soil rocks had been saturated; drilling moistening holes until a lower designed boundary of the softening layer according to its predetermined depth; spacing a boundary of cementation of the moistening holes by a distance being no less, than a depth of an elastic recovery layer, from the coal seam; placing a filtering part of the hole out of the boundary of the saturation zone. Formulae for calculating a pressure for pumping working fluid, a time period for saturation of soil rocks and rate of filtration of the working liquid in rocks of the soil are given in description of the invention.

Patent RU-2043905-C1 (RU)
Title: Method of grinding the workpiece planes
Inventor: IOTOV VALERIJ V
IPC: B24B21/04
Filed: 1992-05-26
Granted: 1995-09-20
Abstract: FIELD: mechanical engineering. SUBSTANCE: workpieces are fed to the storage unit. The abrasive belt is given motion. The workpieces from the storage unit go to the abrasive belt and the latter shifts them to the notch of the guiding clamp. The clamp cross-section is made in the form of a notch having the shape of the longitudinal section of the processed workpieces. The longitudinal section of the clamp consists of the intake and calibrating parts. The generatrix of the intake part is made at the angle α to that of the calibrating part. The angle is chosen as a function of constituents of the cutting forces and the friction coefficient. The workpiece transposition with the speed of the belt movement continues up to the moment at which the upper part of the workpiece comes into contact with the inclined surface of the clamp intake part. When the workpiece comes into contact with the inclined surface of the chute, it becomes detached in the direction of the abrasive belt. The difference in the speeds of the workpiece and abrasive belt movements provides for the allowance removal from the workpiece. The process of the allowance removal takes place while the workpiece travels in the intake part of the chute. After the allowance removal the abrasive belt shifts the workpiece to the calibrating part of the chute where the lapping of the workpiece is exercised with respect to the quality of the processed surface and the final size of the workpiece. The abrasive belt shifts the workpiece from the calibrating part to the receptacle of finished products. EFFECT: enhanced efficiency of grinding. 3 dwg

Title: Rail brake control method
Inventor: JUNG MARTIN DIPL ING
IPC: B61K7/12
Filed: 1997-08-18
Granted: 1998-11-26
Abstract: The method involves controlling a rail brake (GB) with several (k) individual brakes (1-4) for braking individual courses each with several running mechanisms (LW1). The run in speed of each mechanism (LW1) in the brake (GB) is determined. A target run-out speed of each mechanism is provided from the brake (GB). An excess energy in braking is determined from the energy difference between the run-in speed and the target run-out speed.  Each individual brake (1-4) is controlled in either of the discrete switched on or released operating states. During running, the axles of a rotating mechanism (LW1) are impacted simultaneously by one of the individual brakes. The required number of individual brakes to be switched on is determined according to a discrete algorithm.
