is used directly for mineral mining and rich selection operation of machinery. Including mining machinery and mineral processing machinery. Prospecting machinery work principle and structure of the similar mineral mining for mining machinery were mostly identical or similar, broadly speaking, prospecting machinery also belongs to the mining machinery. In addition, mine operations is also used massive crane, conveyor, ventilation and drainage machinery.
Definition: directly used for mineral mining and rich selection operation of machinery. Including mining machinery and mineral processing machinery. Broadly speaking, prospecting machinery also belongs to the mining machinery. In addition, mine operations is also used massive crane, conveyor, ventilation and drainage machinery.
is the direct extraction of useful minerals and mining working with machinery and equipment, including: Mining of metal ore and non metal ore mining machinery; mining coal with coal mining machinery; mining oil used in oil drilling machinery. The first pneumatic disc shearer is Walker designed by British engineers, ca. in 1868 manufacturing success. Eighteen eighties, the United States has hundreds of oil wells using steam power impact drill drilling success, 1907, and rock drill in drilling oil and gas wells, and from 1937 onwards, it will be used for open pit mine drilling.
for underground and open pit mining mining machinery: drill hole by using drilling machinery; digging ore rock in mining machinery and machinery; drilling shaft and drift patio, with boring machine.
Drilling machine for drilling machine and drilling machine two, drill and open-air drilling and underground drill points.
①drill: used in the above medium hard rock drilling diameter of 20 mm to 100 mm, at 20 meters depth of blasting hole. According to its power can be divided into different pneumatic, hydraulic and electric power, internal combustion rock drill pneumatic rock drill, which is most widely used.
②openpit drill : according to the rock breaking mechanism different, divided into rope impact drill, drill, rotary blast hole drill. Cable percussion drill rig for low efficiency, has gradually been replaced other rig.
The downhole drilling: drilling pore size of less than 150 mm underground hole, besides the application of drilling machine can also be used from 80 to 150 mm small diameter DTH drill.
