Field study of DTH hammer operation with rock drilling machines

Mining operations with rock drilling machines actually suffer from insufficient performance of rotary drilling. In this regard, it is proposed to equip drill columns of roller-bit drilling machines, e.g. SBSH-250, with DTH hammers. Furthermore, such DTH hammers are modified by means of installation of an intermediate element between a percussion piston and a drilling tool—a striker head. The article discusses designs of some test benches. One of such test benches was used for the staged field studies aimed to test the proposed design of a DTH hammer. The main idea was to increase the blow energy so that to speed up drilling. Within the set task, the basic variables of the DTH hammer were calculated, and the material was selected to manufacture the striker head. The graphical dependence of the drilling rate and the blow energy is presented. The wanted parameters are determined using the test bench. The improved rock drilling system can increase the drilling rate (drilling capacity) by 2–2.4 times and can extend the life of the rock-breaking tool, which, in its turn, can reduce the cost of drilling.

Keywords: rock drilling machine, DTH hammer, roller bit, blow, rock fracture, drilling rate, drill hole, rock-breaking tool.
