Description

technical field

[0001] The invention relates to the technical field of coal mining support equipment in coal mines, in particular to a large-channel linear-guided top-coal caving transitional hydraulic support for a top-coal caving mining face. Background technique

[0002] The top-coal caving hydraulic support is the key equipment of the top-coal caving mining method. The top-coal caving transition hydraulic support is a special hydraulic support used for the transition section at both ends of the top-coal caving face. The innovation and development of the frame type is the key to the top-coal caving mining technology An important condition and symbol of innovation and development. At present, the frame types of caving transition hydraulic supports mainly include reverse four-link support type, positive link support type and single pendulum support type. These frame types have their own advantages and disadvantages. Accelerating and deepening the understanding of comprehen...
