Embodiment 1

[0046] like figure 1 As shown, the advanced support system for the continuous construction of fully mechanized excavation in the roadway includes the first bracket group 1 and the second bracket group 2 arranged continuously. The first bracket group 1 includes the first self-moving bracket 11, the upper anchor net mechanism 12, the upper anchor The net mechanism 12 is installed on the end of the first self-moving support 11 away from the second support group 2, the left end in the figure;

[0047] The second bracket group 2 includes a second self-moving bracket 21 and two groups of bolt drill parts 22, and the bolt drill parts 22 are vertically installed at both ends of the second mobile bracket 21;

[0048] combine figure 2 , image 3 As shown, in this embodiment, the first self-moving support 11 and the second self-moving support 21 have the same composition and structure. Here, the first self-moving support 11 is taken as an example. The first self-moving support 11 incl...

Embodiment 2

[0064] like Figure 9 As shown, the difference from the first embodiment above is that a third bracket group 3 is added between the first bracket group 1 and the second bracket group 2,

[0065] The third bracket group 3 also includes a third self-moving bracket, which is the same as the first self-moving bracket. The required equipment can be installed on the third self-moving support as required.

[0066] In the end, the first support group 1 is mainly used for the protection of the roadheader, the anchor net mechanism at the front, and the placement of equipment such as dust removal fans. 3 It is mainly used for the protection of the secondary transport belt at the rear of the roadheader to realize the automatic support function. In actual use, the length of the first group of supports is 8.5m, and the length of the second and third groups is 7.1m, which can also be adjusted according to the actual situation. The width is generally 4.7-5m according to the width of the roa...

Abstract

The invention discloses a fully-mechanized excavating continuous construction forepoling system. The fully-mechanized excavating continuous construction forepoling system comprises a first support setand a second support set, wherein the first support set and the second support set are arranged continuously. The first support set comprises a first self-moving support, and the second support set comprises a second self-moving support. Each of the first self-moving support and the second self-moving support comprises a front supporting frame, a rear supporting frame, a front supporting oil cylinder set, a rear supporting oil cylinder set, walking oil cylinders and oil cylinder control valves, wherein the front supporting oil cylinder set is installed at the bottom of the front supporting frame, the rear supporting oil cylinder set is installed at the bottom of the rear supporting frame, the walking oil cylinders are arranged between the front supporting frame and the rear supporting frame, and the front supporting oil cylinder set, the rear supporting oil cylinder set and the walking oil cylinder are all connected with the oil cylinder control valves. The invention further providesa fully-mechanized excavating continuous construction forepoling method. The fully-mechanized excavating continuous construction forepoling system and method have the beneficial effects that parallelworking of tunneling and supporting is achieved, so that continuous working of fully-mechanized excavating construction is achieved, and the problem of supporting exposed working is solved.

Description

technical field [0001] The invention relates to a roadway excavation support system and method, in particular to a roadway comprehensive excavation construction continuous excavation advanced support system and method. Background technique [0002] At present, there are two main construction techniques for tunneling in coal mines: blast tunneling and fully mechanized tunneling (now there are also a small number of shield tunnels, but they are generally in the stage of experimental verification), blast tunneling is generally a structure with extremely hard lithology and a particularly large or small tunnel angle. It is a low-efficiency excavation technology that is not suitable for the use of fully mechanized excavation construction. The fully mechanized excavation technology is adopted in the high-bottom pumping roadway or the coal roadway with the lithology hardness below 7, and the mechanization rate of the roadway mechanized excavation has reached 70%. The fully mechaniz...
