The underground architectonic objects are often located at low depth. This is why, in order to protect objects located on the area or minimize the negative impact of works performed on people and the environment, roadheaders are widely applied, with the use of which excavating takes place in a mechanical way. Boom?type roadheaders deserve special attention in the group of roadheaders. A significant feature of the machines is the possibility of building underground objects of any shape and size of cross?section in ...

The methodology of computer simulation of nonstationary fields of temperatures, concentration and pressure is considered. The computer model of non-stationary heat exchanging process is researched. Decentralization interaction of the active parallel agents is the base for computer implementation. Agents are defined as abstraction of elements of physical system where the modeled processes proceed. Process characteristics are calculated on the base of information on non-stationary fields of temperatures of a wall of...
