Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing and example.
[0017] The model of the hydraulic support 3 on a working face is ZY6000 / 19 / 40, the width of the hydraulic support is 1.5m, the maximum height is 4.0m, the minimum height is 1.9m, and the weight is 16.5 tons. When the working face is stopped, the inclination angle of the two troughs is 20°, and the distance between the level roadway and the exit of the working face is 150m. In order to ensure the rapid and safe withdrawal of the hydraulic support 3, the hydraulic support is now carried out in the track trough (inclined roadway). loading.
[0018] 1. The platform 7 is excavated along the bottom of the track at a distance of 9m from the exit of the working surface. The length of the platform is 5m. The railway is laid on the bottom of the platform and the area below, and safety facilities such as car stoppers, car bars and car bars are installed.
[0019] 2. For t...

Abstract
The invention relates to a process technology used in the coal mining equipment withdrawing process, in particular to a fully mechanized mining hydraulic bracket loading technology in an inclined roadway. Bracket loading in the inclined roadway can be achieved, and a flat car and a railway line are used for outward transportation of a bracket. By digging a platform in the inclined roadway, railways are laid on the platform and the lower area of the platform, and bottoming, run-off elevation and slideway laying are conducted on the upper area of the platform. Two post puller chambers are set upin the inclined roadway, two post pullers are installed and used, and the bracket can be quickly and safely transferred and loaded to the flat car in the inclined roadway. The technology has the advantages that the construction method is simple, the construction speed is high, the outward transportation speed of the bracket is high, and meanwhile the safety can be guaranteed. The technical and economic benefits are distinct.
Description
technical field [0001] The invention relates to the field of moving and withdrawing equipment in fully mechanized mining working faces in coal mines, and in particular to a process for loading supports into vehicles in a roadway with an inclination angle. Background technique [0002] Fully mechanized mining hydraulic support is a commonly used equipment in coal mine production enterprises. It is used in underground production of coal mines to support the roof of the working face, cover the working space of the shearer and the conveyor, and enable the shearer to complete the height of the working face at one time. The coal that has been mined is transported out by the conveyor, and the operation cycle is composed of coal cutting, frame moving, pushing and sliding, etc., to realize the continuous production of fully mechanized mining. The fully mechanized mining support generally weighs about 10 to 30 tons. After the recovery of one working face is completed, it needs to be r...
