Abstract

A mining machine (102) for rock excavation, the mining machine (102) comprising: a rotatable cutting head (104) having rock-engaging cutting elements (108); a holder (110) for holding the cutting head (104), the mining machine (102) being configured to rotate the cutting head (104) in relation to the holder (110); a thrust unit (112) attached to the holder (110); a machine body (114) attached to the thrust unit (112), the thrust unit (112) being movable in relation to the machine body (114); a thrust apparatus (118) for moving the thrust unit (112) in relation to the machine body (114) between a retracted position and an extended position, the thrust apparatus (118) being configured to push the thrust unit (112) in a forward direction, thereby pushing the cutting elements (108) into the rock formation; a hydraulic pump (122); one or more hydraulic consumers (125); and a hydraulic line system (126) for hydraulically connecting the hydraulic pump (122) to the hydraulic consumer (125). The hydraulic line system (126) comprises first hydraulic lines (126a) attached to the machine body (114) and second hydraulic lines (126b) attached to the thrust unit (112), wherein the hydraulic line system (126) comprises two telescopic hydraulic line units (128), wherein each telescopic hydraulic line unit (128) hydraulically connects one (126a) of the first hydraulic lines (126a) to one (126b) of the second hydraulic lines (126b). The mining machine (102) is configured to move the thrust unit (112) and the cutting head (104) back and forth in cutting strokes to cut the rock formation, thereby retracting and extending the telescopic hydraulic line unit (128) with the movement of the thrust unit (112). A method for conveying hydraulic fluid to and from a hydraulic consumer (125) and a method for rock excavation with the aid of such a mining machine (102).
