Vocabulary. Read and learn by heart:

Hole – свердловини

Depth of a borehole – глибина буріння

Operation pressure – робочий тиск

Consumption – витрата повітря

Force of feeding – підсилення подавання

Overall dimensions of a working, m – габаритні розміри видобутку

Mass of a drilling rig (without a set of rods), kg – маса бурового верстата (без комплекту штанг), кг

Mass of a set for delivery – маса комплекту постачання

ПТ48 STOPER DRILL PNEUMATIC

Designed to drill upward holes of a diameter 52-85 mm to a depth of up to 15 m in rock of a strength factor up to 20 units (prof. Protodiakonov scale).

Used in cutting of mine workings, mining of minerals and ores, and in other drilling and blasting works.

Belongs to the class of heavy stopper rock drills of percussion and turning operation with independent telescope feeder for the creation of axle compression to the drilling tool by the rock drill.

Read and learn by heart:

Torque while the frequency of rotation is not less than 1/s, Nm, not less than – крутильний момент при частоті обертів не менше 1/с, Нм

Rated pressure of compressed air – номінальний тиск стиснутого повітря

Telescopic feeder stroke – хід телескопного податника

Overall dimensions, not more - габаритні розміри, не більш

ПТ38 STOPER DRILL PNEUMATIC

Stoper Drill ПТ38 is designed to drill upward inclined holes of a diameter up to 40 mm and into the rock depth equal to 14 m of hardness co-efficient up to 20 units according to prof. Protodiakonov scale, while mine workings drilling and mining.

Belongs to the class of heavy stopper rock drills of percussion and turning operation with independent telescope feeder for the creation of axle compression to the drilling tool by the rock drill.

BUCKET LOADER UNDERGROUND ПКШ

It is designed for mechanization of the loading process of rock while making and cleaning water-diversion ditches, located along the rail track while cleaning mining workings from embankment in the process of holes driving.

Bucket loader can be operated in horizontal mine workings of 2,5 m width. Equipped with a rail gauge of 600 mm, 750 mm or 900 mm of an internal radius of rounding not less than 15m, with a pneumatic line not less than 50 Dy and with a mine lighting network of power in 36 V.

The design of the Bucket Loader provides with:

  • cleaning of water-diversion ditches of 400 mm width and 900 mm depth (lower than the rail heads), located on both sides of rail track at the distance up to 1,8 m (on the axles of a ditch and a track);

  • Loading of rock of bulk density up to 2,5 ton/cub. M of lumpiness up to 350 mm while cleaning mine workings and up to 200 mm while cleaning water-diversion ditches onto transport vehicles of sides height not more than 1500 mm;

  • Comparing to the Loader ПКУ-А, earlier manufactured, while operating Bucket Loader ПКШ, there is an opportunity to overlap the operations of the Bucket Loader’s motion with simulations of the scoop section; motion section is the same as it is on the Loader МПП3 but more simple and safe in operation pneumatic engine is used instead of the hydraulic engine ВЛГ 400.
