Abstract

At present, there is an urgent need to create roadheaders for driving mine workings in medium‑hard and hard rocks. One of the possible solutions to this issue is the creation of a roadheader that destroys rock by percussive action. The development of the design of the working element of such a machine is complicated by insufficient study of rock destruction under impact loading and the lack of parameters necessary for design. For this reason there are still no satisfactory designs of impact mining machines, despite the fact that the first inventions in this field appeared more than a hundred years ago (for example, the Penrice tunneling machine of 1856).
