Selection and application of"three machines"in Hetaoyu Mine
With the development of fully-mechanized top coal caving technology,it has become a consensus in the industry that the com-plete set and intelligent supply of"three machines"equipment such as hydraulic support,shearer and scraper at the working face can effectively solve the contradiction of unreasonable matching of single machines and inconsistent communication protocols.Therefore,we have determined the model and configuration parameters of the"three machines"equipment in the No.2804 working face by studying the selection theory of the"three machines"equipment and combining the supporting data of the surrounding mines of Hetaoyu Mine.The supply from a single manufacturer can improve the matching efficiency and facilitate the unified communication protocol.At the same time,through the solution of some problems affecting mining efficiency in the mining process and the exploration of intelligent ap-plication,the stable production reaches 6 knives/day.
