Mine surveying and geomechanics
The Laboratory performs the following work on mine surveying:
- construction and development of mine surveying reference, and plan and vertical control networks in mine workings, surveying in mine workings and on the land surface, preparing mine surveying documentation and expansion of document collection, staking
and fixing of geometry elements of mine workings, communication lines, boreholes, etc., boundaries of safe mining operations, barrier and safety pillars, protective zones and technical areas of buildings and structures, etc.;
- estimation and accounting ( on the basis of instrumental measurements, mine surveying and geological documentation) of the scope of main mining, construction and assembly processes;
- surveying of buildings, engineering structures, service lines, etc., systematizing of information;
- supervision of compliance of urban underground structure construction projects, design and technical documentation;
The Laboratory personnel participate in the development of measures aimed at the perfection of industrial safety and perform instrumental monitoring of the processes of rock movement, mine workings, buildings and structures located in the areas of mining effect with the subsequent analysis of monitoring results.
Development and design of mine surveying projects, and preparing the reports on the implemented mine survey projects. Besides, the Laboratory designs monitoring station projects and prepares recommendations on the perfection of management and methods of work and implementation of monitoring based on a broad range of achievements of science, technology and advanced practice.
Main tasks and objectives of the Laboratory in the mining complex waste management:
The Laboratory is furnished with modern equipment: for ore processing (crushers, grinders, vibratory cone and ball mills, thermostat, sieving machines); for studying of physical and chemical properties of minerals and mixtures (compression testing machines, ultrasound analyzer of the rock mass strength, laboratory-scale vibratory plate; construction material moisture meter, sclerometer, Vikat apparatus, core drilling device). The Laboratory is also furnished with a KBF 720 constant climate chamber for modeling of any underground conditions, accelerated climate tests for various industrial sectors).
For validation of mineral processing technologies the Laboratory performs the following geological-mineralogical studies:
(solid phase);
with the following: DiSCmini portable nanoparticle analyzer for 10-700 nm diameter particle monitoring, with 10³ - 106 particle/cm³ concentration in the air, including the assessment of toxic nanoparticles; DT-9880 dust particle counter for measuring of concentrations of 0.3 to 10 µm solid particles with 70∙106 particle/cm³ concentration, temperature within a -20ºC to +500ºC range. MKS-01CA1 dosimeter-radiometer intended for the measuring of ambient equivalent dose rate and ambient dose equivalent rate of gamma (X-ray) radiation within 0.1 to 1∙104 min-1∙cm-2 range.
density of beta- and alpha-particle flux from contaminated surfaces and indication of ionizing particles flux within 5 to 3∙104 min-1∙cm-2, search of ionizing radiation sources. Ekofizika-110A precision sound level meter with a set of measuring-software modules, such as P3-80-EN500 and P3-80-E DIN digital meters, for the measuring of harmful physical factors: noise, vibration, infrasound, electromagnetic radiation, etc. DT-9862 high-temperature pyrometer intended for temperature non-contact measurement of the surface in particularly complicated conditions, within a -50°С to 2200°С temperature range.
