Technical Principle and Progressiveness of 110 Coal Mining Method
The 110 coal mining method is a new type of coal mining method characterized by mechanization,automation,informatization,and intelligence.It can improve the recovery rate of coal resources and meet the needs of modern coal mining production to the maximum extent.The 110 coal mining method(i.e.thick coal seam roof cutting and pressure relief gob-side entry automatic mining technology without coal pillars)was analyzed and studied,the basic principle and main technical characteristics of the 110 coal mining method were expounded.The mining method includes a series of key technologies such as constant resistance anchor cable support and advance shaped blasting.The progressiveness of technology of 110 coal mining method was analyzed in combination with traditional coal mining methods.It is concluded that this construction method has the advantages of stable self-created roadway,small excavation amount and high resource utilization rate,and it is suggested to be further popularized in the whole industry.
