Abstract

The invention discloses a winter anti-freezing drilling tool for mining area opencast mining and relates to the technical field of mining equipment. The winter anti-freezing drilling tool for mining area opencast mining comprises a drill bit. A connecting base is welded to the top of the drill bit, and a plurality of equidistantly-distributed through holes are formed in a spiral shape in the bladedirection of the drill bit itself in the side surface of the drill bit. A flow-guiding anti-freezing mechanism is arranged in each through hole correspondingly. Each flow-guiding anti-freezing mechanism comprises a driving motor, heat release mechanisms, connecting zigzag rods, friction rings, flow disturbing pieces and arc-shaped flow guiding pieces. The driving motor is fixedly installed at theinner bottom of the drill bit. The heat release mechanisms are fixedly installed in the through holes. According to the winter anti-freezing drilling tool for mining area opencast mining, based on hot air flow generated by operation of the flow-guiding anti-freezing mechanisms, certain heating is conducted on low-temperature water bodies emerging via drilled holes so that the temperature of the low-temperature water bodies is higher than the freezing point after being in contact with outside air, and thus the circumstance that the water bodies emerging via the drilled holes afflux into peripheral excavated rock powder so that the water bodies are frozen is effectively prevented from occurring.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a winter antifreeze drilling tool for open-pit mining in mining areas. Background technique [0002] As the most important part of various industries, mining provides various resources for production activities, and its mining methods are diversified. Compared with underground mining, open-pit mining has the advantages of full resource utilization, high recovery rate, low dilution rate, suitable for large-scale machinery construction, fast mine construction, large output, high labor productivity, low cost, good working conditions, and production Safety. In open pit mining operations, mining work is still required in winter to meet the production needs of the concentrator. The commonly used mining method in mining is drilling. Drilling tools are used to excavate the soil layer. During winter production activities, there is water in the rock layer. During the perforation...
