COMPLEX MONITORING OF DRALINE OPERATIONS ON COAL DEPOSIT IN PERMAFROST
Difficulties of development of rocks dragline on fields of a zone of permafrost are noted. The methodical approach of integrated monitoring dragline operation based on the application of highly advanced digital devices have been presented. Results of researches of particle size distribution of pieces in a face of a dragline are presented. It is shown that in the course of working off of the block the share of small fraction in a face of a dragline increases. The interrelation of productivity of a dragline with temperature of a blanket of the blown-up massif and the size of an average piece at a consecutive exposure of a face during the summer period is shown. It is shown that with temperature increase of breeds in a face and reduction of the size of an average piece productivity of the excavator increases several times. It is noted that humidity of breed during the summer period doesn't influence excavator productivity. Results of research of the thermal mode in disorder of the rocks which are blown up the permafrost during the periods spring-summer, fall-winter are presented at a consecutive exposure of a face. It is shown that during the spring and summer period negative temperature has impact on temperature of a blanket the massif, saved up in the winter period and solar insolation. During the autumn and winter period temperature in this layer is formed due to the thermal inertia of the massif which has been saved up in the summer and influences of low temperatures of air. For productivity forecast dragline during the different periods of year it is recommended to determine time of a cycle of the excavator by separate empirical formulas.
