Research and Application of Rotating Mining Technology in Fully Mechanized Mining Face
After more than 50 years of mining,the resources in the mine are on the brink of depletion,and the available reserves are under poor mining conditions.The continuity is becoming increasingly tight.In order to more effectively recover coal resources,the corner coal resource blocks are mined through rotating mining method in the 63lower06-2 working face.Before the transformation of the transportation system,the angle between the machine tail of the first belt conveyor and the machine head of the second belt conveyor in the transportation roadway is 161°.The rotating mining conducts to formulate transportation system renovation and roadway reinforcement support scheme in advance,the required materials and equipments are prepared,the on-site mining adjustment range is controlled,and a series of difficult problems such as smooth rotation transition of the machine head,support for the empty roof area and large span area of the machine head,removal of the second belt conveyor machine head,and turning transition of the reversed loader,etc,are solved,achieving smooth turning transition of the working face machine head and ensuring production safety.
