Problems solved by technology

As a result, the bolt (or anchor shotcrete) support speed is slow, so that the excavation speed is greatly restricted, which restricts the ability of fully mechanized excavation equipment and the improvement of mechanized excavation speed

Embodiment approach 1

[0018] Bottom-laying self-moving temporary support system The self-moving temporary support system for fully-mechanized excavation where the moving track is arranged in sections on the roadway floor. The temporary support equipment mainly includes: temporary supports, moving tracks and moving vehicles. This method can be used for excavation of large section. The technological characteristics of the self-moving temporary support system are ( figure 1 ):

[0019] 1). Use fully-mechanized excavator 8 to excavate the coal wall or rock wall, and at the same time use fully-mechanized excavator 8 and belt conveyor to transport coal and rock, stop after excavating 3.0m, and clean the excavation site for 3 minutes

[0020] 2). Lay the moving track support 4 and the moving track 5, hang the net on the coal wall (or rock wall) and the roof, then expand the temporary support top beam 1, raise the temporary support pillar 2, and prop up the temporary support leg 3 , the temporary support...

Embodiment approach 2

[0026] Hanging self-moving temporary support system The moving frame track is suspended in sections under the top beam of the roadway temporary support and the self-moving temporary support system. The temporary support equipment mainly includes: temporary support, moving track and Move the car. This method can be used for small section excavation. The main difference between the self-moving temporary support system and the first method is that the moving track is suspended, and its technological characteristics are ( figure 2 ):

[0027] 1). Use fully-mechanized excavator 8 to excavate the coal wall or rock wall, and at the same time use fully-mechanized excavator 8 and belt conveyor to transport coal and rock, stop after excavating 0.8m, and clean the excavation site for 1 minute

[0028] 2). Install the shifting track frame and shifting track on the temporary support, hang the net on the coal wall (or rock wall) and the roof, then unfold the temporary support top beam 1,...

Embodiment approach 3

[0034] Frame semi-fixed self-moving temporary support system, the moving frame track is fixed on the roadheader and transporter through the track frame, and the temporary support equipment mainly includes: temporary support, moving frame track And moving truck, this method can be used for large, medium and small section excavation. The main difference between this self-moving temporary support system and Embodiment 1 and Embodiment 2 is that the frame-moving track is semi-fixed, and the frame-moving track does not need to be laid and installed, but needs to be dragged (such as image 3 ), its technological features are the same as in Embodiment 1.

Abstract

The invention discloses a fully-mechanized excavating self-moving type temporary support system and a technological method thereof, belongs to the field of large-scale, centralized and automatic fully-mechanized mining and fully-mechanized excavating technology for coal mines and particularly relates to a quick tunneling fully-mechanized excavating system and a technological method. By the aid of the self-moving type temporary support system, a position for performing a tunneling procedure and a position for performing a permanent support procedure in a fully-mechanized excavating process are separated by a certain distance on a tunneling face of a roadway, so that the tunneling procedure and the permanent support procedure are performed in parallel instead of being performed sequentially. The fully-mechanized excavating self-moving type temporary support system and the technological method are mainly characterized in that the tunneling procedure and the permanent support procedure in the fully-mechanized excavating process are carried out separately by the certain distance at the same location of the roadway, so that the tunneling procedures and the permanent support procedure are performed in parallel instead of being performed sequentially, and the system realizes quick fully-mechanized excavating. By the aid of the system, duration of influences of permanent support to tunneling is shortened, the fully-mechanized tunneling speed is multiplied, efficacy of a fully-mechanized tunneling road-header is greatly realized, and production efficiency of a mine is improved.

Description

technical field [0001] The invention discloses a fully mechanized digging self-moving temporary support system and a process method thereof, which belong to the field of large-scale, centralized and automatic fully mechanized mining and mechanized excavation technology in coal mines. Specifically, by adding a self-moving temporary support system, the two main processes of excavation and permanent support in the traditional fully mechanized excavation process are separated from the roadway excavation surface by a certain distance, so that the two processes of excavation and permanent support are separated by sequence. The operation is changed to parallel operation to realize the system and process method of rapid excavation of fully mechanized excavation. Background technique [0002] With the development of fully-mechanized mining and fully-mechanized excavation technology, coal mine production is moving towards high-yield, high-efficiency, large-scale, centralization, and a...
