Problems solved by technology

[0002] At present, coal mine roadways mainly adopt advance support, roadheader operation (roadheader excavation, slag discharge), and permanent support for excavation operations. There are potential safety hazards on the roof; the second is that the excavation needs to wait for the advance support to be completed before proceeding, and the operation is discontinuous, resulting in low operation efficiency

Abstract

The invention relates to a movable advance supporting system and supporting method. The movable advance supporting system comprises a frame moving unit and several double-support frame bodies which are sequentially arranged in a length direction of a roadway, each double-support frame body comprises two single-body supports which are fixedly connected into a whole, and the two single-body supports are arranged in the length direction of the roadway; each single-body support comprise an arc-shaped ejector rod, side rods hinged at two ends of the arc-shaped ejector rod through upper transverse hinge shafts respectively, and jacking oil cylinders hinged to the lower ends of the side rods through lower transverse hinge shafts, the arc-shaped ejector rod and the two side rods form an arch shape matching the section of the roadway, and a first telescopic device for driving the side rods to rotate towards the inner side of the arch around the upper transverse hinge shafts is arranged on the arc-shaped ejector rod; and the frame moving unit comprises a working platform and a driving device for driving the working platform to move in the length direction of the roadway, a second telescopic device is arranged on the working platform, the extending part of the second telescopic device stretches out and draws back in the vertical direction, and a rod clamping device located below the arc-shaped ejector rod is arranged on the extending part of the second telescopic device.

Description

technical field [0001] The invention relates to the technical field of roadway support, in particular to a mobile advance support system and a support method. Background technique [0002] At present, coal mine roadways mainly adopt advance support, roadheader operation (roadheader excavation, slag discharge), and permanent support for excavation operations. There are potential safety hazards on the roof; the second is that the excavation needs to wait for the advance support to be completed before proceeding, and the operation is discontinuous, resulting in low operation efficiency. Contents of the invention [0003] Aiming at the above-mentioned problems in the traditional operation mode, the present invention provides a mobile advance support system and support method, which shortens the time of advance support and empty roof, and realizes the continuous operation of the excavation process. [0004] The present invention is achieved through the following technical solu...
