Abstract

The invention discloses a mine roadway excavation working face temporary support hydraulic device comprising a hydraulic combined support, four graded telescopic jacks, a head temporary support and a tail temporary support. The hydraulic combined support comprises four sets of hydraulic supports composed of top beams, lifting jacks and longitudinal-moving jacks; the graded telescopic jacks are installed on the upper portions of the top beams of the hydraulic combined support; the tail temporary support supporting range serves as the roadway supporting operation space, the head temporary support provides the operation space for muck loading, rock drilling and one-step supporting, and the hydraulic combined support is used for implementing the entire moving of a roadway excavation temporary supporting system; each temporary support comprises a top beam and two hydraulic jacks, the top beams of the temporary supports are fixed to the graded telescopic jacks, the two hydraulic jacks are suspended freely to serve as support legs, and the top beams and the hydraulic jacks are connected through pins. The roadway construction empty roof operation is avoided, surrounding rock can be supported timely, and roadway excavation and supporting parallel operation is implemented.

Description

technical field [0001] The invention relates to a hydraulic device for temporary support of roadway excavation working face. Background technique [0002] Drilling and blasting method and comprehensive mechanized method are mainly used in coal mine roadway excavation construction. At present, most of coal mine roadway excavation work is temporarily supported by metal front-beam advance temporary support. Inch steel pipe, the length is not less than 5 meters; the strength of the hoisting ring and the beam hanger must match the strength of the front beam; the anchor rod of the upper hoisting ring must have enough threads to ensure the firmness of the hoisting ring; The distance between the head-on end face shall not be greater than 0.3m, and it shall move forward in time with the construction. The problems that this kind of temporary support exists have the shortcoming such as personnel enters empty top area operation, labor intensity is big, safety is poor. [0003] The pat...
