Inventor: EHRHARDT WILHELM DR ING
IPC: E21D9/00
Filed: 1975-10-03
Abstract: The procedure for producing boreholes involves rotary and/or percussive boring in underground mines or tunnels. The boreholes (3) for test and stress release and gas extraction purposes are driven if possible at right angles to the direction of active planes (2) of tectonic forces in the strata. The stress-release and gas extraction and test boreholes are first positioned in zones of small reduction and subsequently in zones of a strong reduction of the tectonic forces in the strata. The gas extraction boreholes are driven from the zones of strong reduction of the tectonic forces in the strata. The gas extraction boreholes are driven from the zones of strong reduction to zones of small reduction of tectonic forces. Boring of holes (3) for testing and stress release and gas extraction is stopped when bored powder in the coal is considerably increased without corresponding increase of extracted gas.

Patent DE-2623759-A1 (DE)
Inventor: SALZMANN FRIEDHELM
IPC: F23D11/40
Filed: 1976-05-26
Abstract: The pressure-pulveriser oil burner has a pulveriser nozzle (1) which is arranged in an axially extending cavity (3) of a pot-shaped hollow body (4). The hollow body (4) is surrounded by a coaxially arranged swirler for the combustion air which flows in in an outer air-guiding casing (8). The swirler is intended to create a low-pressure zone downstream of the pulveriser nozzle (1). Arranged at the open end of the hollow body (4), downstream of the pulveriser nozzle (1), is an incandescent body (11) which glows when the flame burns and on the rear side of which an air-screening body (12) is provided. Arranged between this air-screening body (12) and the pulveriser nozzle (1) is a ring of air nozzles (14) which project radially into the cavity (3) and which serve to conduct the combustion air, which flows in in the outer air-guiding casing (8), into the cavity (3). As a result, an air curtain is produced on the side of the incandescent body (11) and of its air-screening body (12) facing the cavity (3). A soot-free and completely stabilised burning of the flame is thus achieved, irrespective of the dimensions and of the design of the combustion chamber of the associated heating boiler. <IMAGE>
