Designing Project of Double-hydraulic Prop Support Program in Mining Face

In view of current mining and blasting mining face hanging hinged metal roof beams and pillars of moving hydraulic process deficiencies,here gives a new program which uses double-hydraulic mining in the mining face and artillery support,as well as double-use hydraulic methods,and finally to carry out the mechanical analysis,to draw double-hydraulic mining face in the merits of supporting.
