Problems solved by technology

[0003] The N00 mining method is a new coal mining technology, which can leave a roadway during the coal mining process, but the force around the roadway will change during the coal mining process, which will easily cause problems such as roadway collapse or rock mass fall, which is serious Threatening the life safety of the staff, so the support of the reserved roadway is the key guarantee for the implementation of the N00 mining method

Abstract

The disclosure provides a roadway retaining area support system based on the N00 mining method, and relates to the technical field of coal mine roadway support. The support system includes a retaining roadway, a protective net, an end support assembly and a portal support assembly, wherein: the retaining roadway has a first side wall and a second side wall arranged oppositely and is connected to the first side wall The roof between the roof and the second side wall, and the roadway retained is a roadway formed by the operation of the hook machine device; the protective net is fixed on the surface of the roof, the first side wall and the second side wall, and is used to prevent rocks in the roadway body drop; the end support component is set at the corner of the roadway and is against the protective net; the portal support component is located on the side of the shearer away from the coal mining face and is used for retaining the roadway. The roadway is supported in real time. The support system of the present disclosure can prevent the rock mass in the top and side walls of the roadway from falling, form a stable roadway side, and ensure the safety of workers.

Description

technical field [0001] The present disclosure relates to the technical field of coal mine roadway support, and in particular, relates to a roadway retaining area support system based on the N00 mining method. Background technique [0002] As one of the main energy sources, coal is widely used in daily life and industrial production. With the development of science and technology, people's demand for coal resources is increasing, and efficient mining of coal resources is particularly important. [0003] The N00 mining method is a new coal mining technology, which can leave a roadway during the coal mining process, but the force around the roadway will change during the coal mining process, which will easily cause problems such as roadway collapse or rock mass fall, which is serious Threat to the life safety of the staff, so the support of the reserved roadway is the key guarantee for the implementation of the N00 mining method. [0004] It should be noted that the informati...
