Abstract
The article is devoted to the problem of reducing the harmful effects of toxic substances on the human body in the work of the chain trench excavator. Typical load variation on the shaft of the diesel internal combustion engine during the working process associated with changes of soil conditions leads to increased content in the exhaust gases of carbon monoxide, nitrogen oxides, soot. The article describes a method that allows the engine to operate at rated speed. By fixing the nominal mode, optimal redistribution of engine power between the working body and the mover, it is possible to achieve maximum combustion of the fuel, resulting in reduction of harmful gases.

Abstract
In the paper the influence of mineral nanodisperse silica component on reactivity of cement from different producers is studied. Method of introduction of mineral nanodisperse modifier in binding mixture is proposed. Differences of chemical composition of the studied Portland cements are reflected on features of relationship with nanodisperse component. Optimization of content features of nanodisperse component introduction into cement system as well as hardening conditions allow varying its reactivity and promote to intensification of hydration process of clinker minerals, Portlandite fixation into additional C-S-H phases, that leads to strengthening of cement stone structure. Generally, enhancement of efficiency of cement binder is provided with reducing of clinker component up to 20% and improving of strength characteristics of composite up to 20%.

Abstract
The data on obtaining active mineral additives from sapropelic raw materials while their burning at 850 … 900оС and afterpowdering are presented in the article. Properties of paste matrix with sapropel ashes were studied and the mechanism of sapropel ashes influence was discovered. Introduction of ashes into Portland cement PC 400 and PC 500A0 together with Glenium plasticizer increases paste matrix strength and decreases its water absorption. Ash adding makes a puzzolanic effect on the cement bonding agent and causes the formation of stable calcium aluminate forms due to the alumosilicagels content.

Abstract
This article addresses the problem of reducing costs in the operation of crushing and milling equipment, associated with high consumption of lubricant, as the volume of lubrication systems of crushing and milling equipment can be up to 60 m3. To reduce the costs associated with the replacement of the lubricant in the lubrication system of grinding equipment, is necessary to create a tank in which the cleaning process of the lubricant would pass the time, and friction unit received the necessary oil purity. For this it is necessary to install a tank weir lubrication system, thereby dividing it into two parts, into the sump tank itself. Currently, there is no reasonable method of installing weir, it is usually set in the middle of the tank. In this paper we propose a generalized method of calculation of the tank sump. Thanks to it is possible to choose the place of installation weir in accordance with the specific operating conditions.
