Joint technologies of mining machinery
UPP “Niva” acquired the controlling share of JSC “LMZ Universal” in order to manufacture the first belarusian mining complex with a shearer. Join of two leading mining machinery enterprises allows starting works on designing and manufacturing the mining complexes with shearers for ore mining by long mining pillars. Such machinery groups are acknowledged world practice; they show big advantages of combined engineering approach for designing mining equipment considering mutual impact of other equipment used in a face and specific mining and geological conditions. As a good example of success there are such groups as Famur and Kopex (Poland), Joy and Caterpillar (USA). Complex delivery of equipment which was coordinated while designing decreases expenses on keeping engineering staff of a mining company as well as value of investments and operating costs. Exactly what is highly appreciated on the world mining market.

JSC “LMZ Universal” was set up on 25.07.1995 on base of the Soligorsk mechanical foundary, which in its turn was an assign of the repair and mechanical plant built on 15.08.1977. The Plant was planned for production and repair of equipment used in potash and chemical industries.
Commissioning of a profile bending machine.
In order to provide more services on metal working the Company commissioned a profile bending machine with 30 kW capacity.
A profile bending machine with 3 drive rollers is designed for bending the different profile types, it can bend any angle in one rolling. A machine is controlled using a mobile control panel. Standard set consists of a digit indication unit and 3-axes hydraulic unit for setting an optimum angle.
Lightning Equipment
Many years of design and survey work of our Company ended in creation of an LED light for use in underground mining faces. Based on suggestions and requests of operating staff a light is designed to create minimum troubles during moving of a personnel in a face, maintaining roof supports as well as to guarantee required extension of low faces and parameters of clear passage. Pilot batch of lights will be tested in the Krasnoslobodsky Mine, Face No. 3Top (JSC “Belaruskali”).

Our Company continues a survey work in manufacturing a pilot model in order to design a mining light of next generation with maximum weight 1 kg. This new light will need a minimum space in a mining face, will be easy to disassembly from a roof support section for local lightning of repair or other works. Overall dimensions of a new light will allow not only to install it completely in a roof support section but also to foresee its magnetic attachment to a roof support bar.
New range
New type of roof supports has been presented: K8 and K9. Roof supports are designed for longwalls of new Krasnoslobodkiy mine of "Belaruskali".

Tests of roof support for Kuzbas mines
On request of JSC “United Machinery Technologies” (Russia) tests of mechanical roof support 1KM144KC for “Anzherskaya Uzhnaya” (Kuznetsky Coal Basin) are carried out. Range of adjustment - 2000-2800 mm, weight - 13100 kg. Tests are carried out in accordance with GOST R 52152-2003 and targeted to confirm the roof support strength properties after some engineering changes.
Hydraulic cylinders for ArcelorMittal
JSC “ArcelorMittal” (Timertau, Kazakhstan) is a new Customer of UPP “Niva”. Two hundred and nine hydraulic cylinders GM 15/29U for the underground mechanical roof support are manufactured and shipped for the coal mine in Shakhtinsk, Karaganda Region. A cylinder has rod outer chrome-plating and liner inner chrome-plating, operate by pressure 32 MPa, hydraulic extension – 700 mm, hydraulic extension by using mechanical insert - 1218 mm.
