Abstract
A guide for a mineral mining machine, such as a plough, is composed of guide structures at the mineral face sides of the pans of a scraper-chain conveyor. Each guide structure defines upper and lower passages through which a chain for driving the machine passes. The passages are closed off from the mineral face side by a side plate or cover and from the top by means of a head plate. The head plate is detachable and is secured to, or located against, the side plate. The head plate and side plate have upstanding projections which form part of a guide rail for the machine. A foot plate projects beneath the lower passage to support the machine on the floor of a mine working. The guide structure preferably has reinforced end pieces fabricated by casting and the head plate lies between corresponding wall portions of these castings.
