Zusammenfassung:The invention relates to hydraulic equipment of mine development machines for control of its movable units at penetration of mine workings at underground development of minerals. Hydraulic system of mine development machine includes oil station and oil tank connected by pipelines with controllers and distributors of flows to hydro-drives of caterpillar trolleys and hydro-cylinders of control of executive devices, thrusts of machine in horizontal plane and drill unit, differing with fact that oil station of machine is equipped with two axial-piston pumps with varying productivity and one twin pinion pump, to hydraulic system one spark-safe hydro-distributor with electric control is included, this makes it possible to perform control of machine in semi-automated mode simultaneously with two blocked hydro-drives and separately in manual mode, and in hydraulic control system of executive devices, conveyor, grab screens, thrusts of machine in horizontal plane, drill unit, velocity propel switch the hydro-distribution block is used, with hydro-distributors that have mounted-in hydro-locks, and oil tank is equipped with discharge filter, at that connection of pipelines is arranged as "O". Simplification of system of pipelines of hydro-system of machine is achieved, this makes it possible to perform free access to units and elements of machine at mounting and operation, provides possibility of control of both caterpillar trolleys in manual and semi-automated modes, increase of efficiency and reliability of hydraulic system of control of machine, decrease of volumes of discharge of oil flows to oil tank under pressure, decrease of temperature of oil in hydro-system and temperature round the machine, purification of all the volume of oil. Винахід належить до гідравлічного обладнання шахтних прохідницьких комбайнів для керування його рухомими вузлами при проведенні гірських виробок при підземній розробці корисних копалин. Гідравлічна система комбайна шахтного прохідницького включає маслостанцію і маслобак, сполучені трубопроводами з регуляторами і розподільниками потоків в гідродвигуни гусеничних візків і гідроциліндри керування виконавчими органами, розпорами комбайна в горизонтальній площині і буровою установкою і відрізняється тим, що маслостанція комбайна обладнана двома аксіально-поршневими насосами змінної продуктивності і одним здвоєним шестерінчастим, в гідравлічну систему включений один вибухоіскробезпечний електрокерований гідророзподільник, який дозволяє з
