Embodiment Construction

[0017] In FIG. 1, a very schematically simplified illustration of a drum mining machine 1, in particular for mining coal in underground mining, has a drum mining machine body 2, which It is possible to travel on a transmission layer (triebstock) which is arranged parallel to the conveyor (not shown) in the working plane. Mounted on the main body 2 of the drum mining machine are support arms 3 for each of the two directions of travel of the drum mining machine 1 , on which a cutting drum 4 is rotatably supported for each direction of travel, The cutting drum is equipped with a plurality of picks (not shown) as machining tools, with which the ore to be excavated, in particular such as coal, is excavated on the excavation face. A water circuit system not shown in FIG. 1 is integrated in the support arm 3 and in the cutting drum 4 in the main body 2 of the drum mining machine. The drive system of each individual device and the cooling water circulation loop of the motor and a spr...

Abstract

The invention relates to a shearer loader for underground mining, with cutting drums for each direction of travel, with a cooling-water circuit (30) for cooling the drive motors (31, 32), with a spray system comprising at least one spray-water circuit (25A, 25B) with a respective feed line (23A, 23B) to the tools of the cutting drums (4), with a common water connection (1) for the water circuits, and with valves assigned to the water circuits for switching the circuits on or off. Provision is made according to the invention for return lines of the cooling-water circuit to have a respective switching valve (37A, 37B) arranged therein which is connected to one of the feed lines and via which the cooling water can be fed as spray water to the cutting drums as required.

Description

technical field [0001] The invention relates to a drum mining machine for underground mining, comprising a drum mining machine body, a cutting drum fixed on a support arm for each driving direction of the drum mining machine, a plurality of cutting drums for Drive motors for moving the drum mining machine and for moving the cutting drums, at least one cooling water circuit for cooling the drive motors, a spray water circuit including a supply line each with a cutter for the cutting drums The sprinkler system of the circuit, a preferably common water connection for each water circuit, and a plurality of valves assigned to each water circuit for switching on or off the water circuit. Background technique [0002] During underground mining of minerals, in particular coal mining, it is provided to spray spray water through nozzles in order to prevent dust on the excavation surface to be excavated. Most of the spraying of the working surface here is realized by the power support...
