发明名称 DEVICE TO EXPAND HOLES MECHANICALLY AND THERMALLY
摘要 FIELD: mechanics, mining. ^ SUBSTANCE: proposed device incorporates a burner with rock destructing elements, line to feed air oxidiser, line to feed fuel, dust-and-gas suppression unit, pipe to withdraw a hot gas-vapor flow, control board and adsorber representing two concentrically arranged cylinders with adsorbent arranged there between the propose device differs in that the smaller cylinder is made in bimetal. Note here that the inner wall material features heat conductivity factor 2.5 to 3.0 times higher than that of outer wall material. ^ EFFECT: higher efficiency in prolonged operation due to invariable high quality of air drying. ^ 2 dwg
