“…Таким образом, приведенные результаты исследований показывают эффективность использования разработанной добавки в топливо ДГЛ [23,26]. Ее применение позволяет значительно снизить концентрацию вредных выбросов в горных выработках шахт, что, в свою очередь, приводит к улучшению условий труда подземного персонала по химическому фактору [5,10].…”

Equipment with diesel engines is used in all mining enterprises. Monorail diesel transport is of great importance in coal mines, as it facilitates the heavy labor of workers when transporting materials and people, fixing mining workings, refueling and repairing equipment, which leads to an increase in the speed of tunneling operations. Reducing the concentration of harmful gases from diesel-hydraulic locomotives at the workplaces of coal mine locomotive drivers can be ensured by the use of additives to diesel fuel that reduce the volume of harmful gas emissions during the operation of diesel-hydraulic locomotives. Additive ester-based on vegetal oil in the amount of 5 mass % in a mixture with hydrotreated diesel fuel reduces the concentration of carbon monoxide by 19-60 %, nitrogen oxides by 17-98 %, depending on the operating mode of the engine, the smoke content of the exhaust gases is reduced to 71 %. There is an improvement in working conditions at the workplace of the driver of a diesel-hydraulic locomotive by the chemical factor due to the reduction of the class of working conditions from 3.1. to 2.

A method is proposed to reduce dust formation from technological roads during open pit mining. It is suggested to use a solution based on flaxseed cake, instead of only water, for irrigation the technological roads. It can wet the roads more efficiently. The frequency of watering can be significantly decreased, thereby the employees working time can be optimized to reduce harmful effects on health. The costs for oil and fuel also will be decreased. The calculation of costs included the cost of labor, electricity, fuel for the sprinkler, repairs, depreciation and others. Also, a SWOT analysis of the project was performed to justify possible risks, including economic ones, associated with the implementation and application of the proposed method. It was calculated, an economic effect can be achieved in amount of about 1.5 million rubles per year at the Alexeevsky enterprise.

“…Целью работы является разработка профилактических средств (ПС) на основе нефтепродуктов с добавлением тяжелых нефтяных остатков для улучшения низкотемпературных свойств ПС и их способности к пылеподавлению в зимний период, а также вовлечение растительных полимеров в качестве альтернативной сырьевой базы для получения летних пылеподавляющих составов [6]. Летние составы на основе водных дисперсий являются высокоэкологичными и эффективными, в работе [20] авторы исследуют жидкие смазочные материалы на водной основе, которые могут действовать как эмульгаторы в присутствии даже небольшого количества масла.…”

Dust control in summer and winter periods is a topical problem associated with conducting open pit mining operations; however, at negative temperatures the additional requirements are imposed on dust suppressants. Preventive compositions are proposed, in which light and heavy gas oils, obtained from catalytic cracking and delayed coking, are used as base components. Involvement of heavy fractions allows to increase the flash point, thereby reducing the flammability of dust suppressant, improve its adhesion properties by increasing the content of polyaromatic hydrocarbons and reduce the cost of the final product. In order to improve low-temperature and adsorption properties of developed dust suppressants, heavy oil residues (cracking residue and tar) are included in their composition in various concentrations: 2-10 wt.%. Alternative compositions of dust suppressants, obtained by water emulsification of vinylated alkyd oligomer, are developed; the ability of this dispersion to form strong films on dusty surfaces is examined. The efficiency of using aqueous solution of vinylated alkyd oligomer as a summer dust suppressant is demonstrated. The results of this study include the development of new preventive compositions with improved low-temperature properties and confirmation of the theoretical part of the study by the results of performance tests on a laboratory facility.Alternative compositions of dust suppressors have been developed, which were obtained by emulsifying a vinyl alkyd oligomer (VAO) in water; the ability of this dispersion to form strong films on dusty surfaces has been studied. The efficiency of using an aqueous solution of vinyl alkyd oligomer in the summer period as a dust suppressant is shown. The results of this study are the development of new prophylactic formulations with improved low-temperature properties and confirmation of the theoretical part of the study by the results of tests of operational characteristics in a laboratory facility.
