METHOD FOR CUTTING MINE WORKING AND CONCURRENT FORMING COMMUNICATION PROFILE AND DEVICE FOR IMPLEMENTING THE SAME Russian patent published in 1997 - IPC

FIELD: mining. SUBSTANCE: method for cutting mine working includes supply of moulding sand under pressure to moulding head. Liquid components are supplied through different piping to form the moulding sand. The components are mixed in the piping to form solid in the form of communication profile. Device for implementing the method includes profiling head and support lid related to the pipeline for supplying the moulding sand. Working chamber is there in the profiling head. Profiling tubes are placed in the profiling head. Upper ends of the tubes are made to agree with the piping supplying the components of the moulding sand. Lower ends of the tubes are to agree with the chamber bottom. Internal surface of the chamber is covered with anti- friction material. EFFECT: higher productivity. 5 cl, 5 dwg
