Abstract: The comprehensive mechanized coal mining equipments cannot be used normally due to problems such as failure, wear and aging after a certain period of time and a series of equipment maintenance should be needed. Due to many factors such as the complicated structure of the equipment, different operating conditions, various specifications and sub - series, and different abilities of maintenance workers in various mines, the equipment maintenance quota system is extremely difficult, and the project cost is extremely inconvenient to implement. Therefore, on the premise that our country is still in the blank field at present, we have carried out the work of compiling the maintenance quota of comprehensive mechanized coal mining equipments without reference. In this thesis, we have studied the process of compiling the maintenance quota of comprehensive mechanized coal mining equipments deeply, and put forward a set of feasible methods for compiling the quota. At the same time, we expound the problems and difficulties encountered in the process of compiling the quota and the corresponding solutions, and hopes to give some supports to the perfection and perfection of the maintenance quota of comprehensive mechanized coal mining equipments.
