Substantiation of the design and parameters of the device for regulating the air flow in down-the-hole hammers of roller-cone drilling rigs

Many Russian quarries are located in inaccessible areas with harsh climatic and mining and geological conditions. Also massifs of mined rocks are often quite variable in hardness and fracturing, so to increase the rate of drilling, drilling rigs with submersible pneumatic hammer for drilling can be used. The article deals with the improvement of blast hole drilling by a roller cone drilling rig with a submersible pneumatic hammer. An upgraded submersible pneumatic hammer with an air damper through which a regulated air flow passes is proposed. The results of laboratory research on determining pressure losses at the air slide are given and it is shown theoretically that regulation of air flow entering the pneumatic hammer can be reduced in a given range by opening or closing the air slide. Increasing the drilling speed of self-propelled equipment, by using submersible air hammer over a roller cone bit, will reduce the drilling cost. As part of the study, an improved drilling rig with a downhole hammer controlled by a radio receiver was developed. A structural or morphological analysis was made to justify the directions of the drilling equipment modernization. A calculation was made, which was performed in the program Ansys Discovery R2. Static axial load on the cone was modeled.

Keywords: open-pit drilling machine, submersible pneumatic hammer, roller cone bit, impact, rock destruction, drilling speed, air flap, borehole.
