Abstract: For low coal caving efficiency, poor coal caving quality and other problems existing in manual coal caving control mode of fully-mechanized top coal caving working face, an automatic memory coal caving control method was proposed by referring to memory coal cutting control idea of shearer. Automatic memory coal caving control obtains memory coal caving control data through exemplary learning. Electro-hydraulic control system of hydraulic support controls position and attitude of coal caving mechanisms of hydraulic support according to the memory coal caving control data, so as to realize coal caving quantity control through adjusting coal caving opening degree. Meanwhile, the coal caving quantity is calculated by a relationship model between position and attitude of the coal caving mechanisms and coal caving quantity, so as to correct the memory coal caving control data for avoiding overload of rear scraper conveyer. The method is applicable to top coal caving working faces which have stable coal seam with little thickness change.
