The parameters of the monitoring system of the electrical haulage shearer were mainly used to define the environmental parameters of system operations, including the parameters displayed at the client terminal and the parameters of network transmissions, and the geological parameters, mining parameters, gateroad parameters, the parameters of the scraper conveyor, the parameters of the hydraulic support, and the parameters of the shearer and its accessories.
The method can be used for the following purposes: a) to compare the operational qualities of motor trucks with different parameters in quarries of the deep or hillside types; b) to find the technically and economically viable range of application of motor vehicles of various powers and load capacities in open-cut mine workings; c) to plan the working forces of motor dump trucks and to normalize the indices of operation of the dumping-transportation complexes in quarries with given volumes of workings with known technological schemes of transportation of rock, of parameters of the loading equipment, of physicomechanical properties of the rock, and of the indices characterizing the mining-technical and road-transport conditions of exploitation of the motor transport.
Special care must be taken since some potential antiblock minerals (like talc) act as nucleating agents, changing completely mechanical and optical properties of the film even in small quantities. Finally, the hardness in combination with particle size of the mineral governs the wear at least on the extruders used to produce the masterbatch. Additionally, minerals with matching refractive index do not deteriorate the optical properties (transparency, haze) of the films.Particle sizes chosen are in the range of a fraction of the film thickness with special care taken to eliminate any oversize in order to avoid blocking of nozzles or partial film rupture during processing. Also the absence of impurities (like iron oxides) promoting the oxidization of the polymer has to be taken into account.
