In the experimental work, linear coal cutting was done by using two different conical picks: (1) conventional pick made up of cemented carbide tip; (2) a newly developed hardened pick made up of cast iron plus 21% (by weight) mild steel [19]. Each conical pick was provided five different tilt angles- 0°, 7°, 17°, 27° and 37°.
