Through the mine pressure theory analysis, the design method of anchor rod (rope), gob-side entry retaining that combined support of bolt, bar, and wire mesh, cooperate with the design of single hydraulic prop and intersection hinge roof supporting, using special windbreak for airtight goaf, implemented no wall supporting. Through the mineral pressure observation, fixed a supporting parameters, and innovative solved the Rongtai Mine technical problems under the condition of hard roof. Implementing gob-side entryretaining technology, provided the new development direction for similar geological conditions.
