Machine MSZ-3
In order to improve the technical and economic efficiency of blasting operations for smoothwall blasting, including the process of bench levelling, JSC NITRO SIBIR, for the first time in Russia, has developed a technology for mechanized smoothwall blasting, which makes it possible to abandon expensive and time-consuming garland charges for smoothwall blasting.
The MSZ-3 vehicle is designed to transport non-explosive components of a waterproof emulsion explosive (EE):
- "Sibirit" type emulsions (UN number 3375, class 5.1 according to ADR);
- gas generating additive (GGD);
- solution of water irrigation (VO);
GGD and VO are not dangerous goods according to ADR classification),
mixing of the indicated components and manufacturing of "Sibirit®" type explosive explosives in the process of loading contour wells, as well as small-diameter wells in open-cast mining in all climatic conditions at an ambient temperature from -50°С to +45°С.
The machine is based on four-axle chassis of category N3 or N3G that meets the requirements of ADR with a load capacity of at least 6 tons: MAZ 4x2, KAMAZ 4x2 and 4x4, Scania 4x2, 4x4, MAN 4x2, 4x4 and others.
Machine Composition:
1. Chassis KAMAZ-43502-0003036-D5
2. Container with emulsion.
3. Hydraulic system.
4. Automatic dosing system (SAD).
5. Drum with charging hose.
6. Capacity VO (water irrigation).
7. GGD1 tank (gas generating additive).
8. GGD2 tank (gas generating additive).
9. Dosing pumping equipment with technological piping and a mixer of components.
10. Subframe with mounting brackets.
11. Palfinger PC 2700 compact crane-manipulator.
12. Automatic engine fire extinguishing system.
The machine is equipped with a system for counting the weight of components loaded into the well.
To reduce heat losses, the outer surfaces of the tank block are covered with thermal insulation.

MSZ-20UT
Mixing-charging machine MSZ-20UT (Universal), type MEMU according to ADR classification according to ADR EU 2015, complies with the requirements of the "technical regulation on the safety of wheeled vehicles of the Customs Union", is intended for the transportation of components and the manufacture of them in the process of loading industrial explosives of the following types:
- emulsion explosive (EE), class 1.5D, UN No. 0332 according to ADR;
- granular explosive type ANFO, class 1.5D, UN No. 0331 according to ADR;
- mixed explosive, class 1.5D, UN No. 0332 according to ADR.
Mixing-charging machine MSZ-20UT, depending on the operating conditions, is manufactured in climatic modification "U" (temperate climate, ambient temperature from -40°C to +40°C), "T" (tropical dry and humid climate, ambient temperature environment from -10°C to +45°C) according to GOST 15150-69.
The machine is based on an ADR-compliant four-axle chassis of category N3G, MAN TGS 41.400 8x8, or a similar chassis.
Mixer-charging machine MSZ-20UT can also be based on the chassis category N3, N3G: MAN TGS 41, 8x4, 8x6, or similar chassis.
To charge granular explosives, the machine is equipped with a rotary mixing screw, which allows charging wells at a considerable distance on the side and behind the machine.
The service life of the machine is at least ten years.
Unit resource (without chassis) - 120 thousand tons before overhaul, subject to timely maintenance in accordance with the operation manual. Further extension of the service life is possible after the commission examines the unit and obtains an industrial safety expert opinion indicating the further service life.
