- What is110 method?
"110 method" is a roadway, a working face, zero coal pillar construction method. Compared with the traditional longwall mining "121" method, the "110 method" only needs to dig one gateway roadway, and the other roadway is automatically formed by cutting the top and relieving the pressure. The working face changes from "jump mining" to continuous mining, and can realize Y-shaped ventilation and effectively reduce the periodic pressure of the roadway. The safety and economic benefits are very outstanding,Acclaimed by the industry"The Third Technological Change in Mining".The "110 method" is supported by the theory of "cutting short boom beam" proposed by academician he manchao, and uses mine pressure to cut off the pressure transmission of part of the roof rock mass on the side of the goaf, and then uses mine pressure and rock mass fragmentation and expansion characteristics to realize automatic roadway formation and coal pillar-free mining.
110 method inAcademician He Manchaodominated, organization-relatedMore than 40 equipment enterprises have set up 110 innovation alliance. InAutomatic roadway formation by roof cutting and pressure reliefUnder the demand of the construction method, a number of special equipment such as cutting top drilling rigs and supporting drilling tools were born and widely used.
