The parameters of the BelAZ-75131 heavy dump truck im- proved model using gas-diesel mixture are given in the paper. The moni- toring analysis of the conditions and operation indicators of BelAZ-75131 heavy dump truck using diesel and gaseous fuels is done. Numerical and percentage values of the replacement of diesel fuel with liquefied natural gas when transporting exploded rock mass are determined; the volume of diesel fuel and liquefied natural gas consumption has been established. The analytical dependence to calculate the cost per unit of energy during trans- portation by mining dump trucks with gas equipment is determined. The energy estimation of diesel and gas-diesel mining dump trucks operation is given.

The article examines the problems that the station areas of the largest cities face in the process of their development. The article reveals such concepts as the landscape-recreational frame of the territory, its functions, the search for possible reserves for spatial development and improving the quality of the ecology of the environment. Natural and anthropogenic factors influencing the formation and operation of the frame elements are analyzed.
