The invention relates to the field of roadway excavation, and discloses a roadway advance support device and its use method, comprising: several sliding frames hinged in sequence; the sliding frame includes: a first sliding structure and a second sliding structure; the first sliding structure includes : the first slide and the first drill assembly; the second slide structure includes: the second slide and the second drill assembly; the first drill assembly is slidably arranged on the first slide; the second drill assembly is slidably arranged On the second sliding member; the first sliding member is slidably arranged on the second sliding member. The roadway advance support device provided by the present invention improves the condition of the surrounding rock fragmentation when the bolter digging unit excavates the coal and rock mass, and reduces the subsequent Difficulty of construction. The advance drilling of steel brazing shortens the advance support time, improves the surface protection stiffness of the support system, and makes the surrounding rock structure more stable after the roadway excavation is formed.
Description
technical field [0001] The invention relates to the field of roadway excavation, in particular to a roadway advance support device and an application method thereof. Background technique [0002] Rapid excavation of coal mine roadway is one of the technologies urgently needed in coal mining in my country, especially when the surrounding rock of the roadway is broken. During the excavation process of broken surrounding rock roadway, there are a series of problems such as leakage of broken surrounding rock, small allowable roof control distance of roadway excavation caused by slabs, poor surface shape of roadway surrounding rock, and difficulty in installing support components such as surface protection anchors and cables. . [0003] Among them, the broken surrounding rock environment will cause the following types of mine pressure occurrence accidents: ① mosaic-type surrounding rock falling accidents; Roof fall accident due to surrounding rock fracture; Among the above-men...
