Embodiment Construction

[0013] A construction technology for turning and excavating with a hanging loader. The roadheader 8 excavates to the inflection point in the roadway 4. Before the roadway is ready to turn to Hengchuan 5, as figure 2 As shown, select 2 points (A, B) along the direction of the roadway at the roof of the roadway 4, place two lifting anchors at each point, connect the two anchors with anchor chains, and fix the steel wire rope 1 on the two strands. Between the anchor chains; then select a point C on the roof of the roadway, and a point D in the roof of Hengchuan, and place two lifting anchor rods at each point, connect the two anchor rods with anchor chains, and fix the wire rope 22 on Between the two strands of anchor chains; select a point E along the direction of the roadway at the roof of Hengchuan, place two lifting anchors at each point, connect the two anchors with anchor chains, and fix the wire rope 33 on the two strands of anchors between chains;

Abstract

The invention relates to a coal mining excavation process, in particular to a turning and excavation construction process of a hanging loader. To solve the problems of improving the safety production factor, improving the tunneling efficiency, and reducing the labor intensity of workers in the tunneling of the inflection point in coal mine mining, the steps are: when the roadheader excavates to the inflection point in the roadway, before the roadway is ready to turn, the roadway roof and Hengchuan roof Three steel wire ropes are installed between them. When turning and excavating, the tail of the loader is hung on the wire rope through the pulley and the steel wire rope. The belt is laid under the loader, and the loader can follow the movement of the unit and slide along the wire rope; The turning angle of the machine is increased, and the position of the lifting point on the wire rope is constantly adjusted, and the position of the loader is hoisted by three sections of wire rope, so that all the tunneling units turn into the Hengchuan and realize continuous coal output.

Description

technical field [0001] The invention relates to a coal mining excavation process, in particular to a turning and excavation construction process of a hanging loader. Background technique [0002] In coal mining construction, during the roadway excavation process, when turning to the turning point such as the Hengchuan position or the cut eye, the roadheader is generally used to drag the transfer machine to turn the construction. Its construction location and method are as follows: figure 1 As shown, the construction technology has the disadvantages of coal cutting, coal loading, and coal transportation when the machine is withdrawn and the coal is discharged, and the excavation efficiency is reduced; A large amount of coal was spilled behind the unit and the transfer machine, especially when the 4th to 14th rows were turned and constructed, almost all of it was sprinkled behind the unit, and the amount of manual coal cleaning was very large. Contents of the invention [...
