Soft coal seam drilling and extraction complete sets of technical equipment
Soft outburst coal seam drilling and gas extraction is an industry problem, due to poor permeability of coal seam and gas pressure, drilling process is prone to collapse, stuck drill buried drill and
The phenomenon of gas injection hole leads to low efficiency of gas extraction and long drainage cycle, which seriously affects the safety production of coal mines. In view of this problem, the lower screen pipe gas extraction worker can be used.
Art technology, and in order to ensure the effective lowering of the screen, we directly lower the screen without returning the drill after hole forming. The process uses large diameter wide guide vane drill pipe or screw.
Drilling tools such as rotary grooved drill pipe and large and large hole open-close drill bit realize the lowering of screen pipe in the full hole section of the inner hole of the drilling tool, effectively ensuring the lowering rate and greatly increasing the gas extraction efficiency.
