Abstract According to the collapse column produced by the tunneling operation problem in Shanxi Jingu Mine, the scientific system of the construction scheme was made. Using chemical grouting reinforcement in excavating roadway roof and shed supporting technology successfully went through the collapse column, a set of safe and fast through the collapse column in the roadway drivage in construction technology was summed up in the process, which provided reference for heading roadway quickly through collapse column in similar situation.
