Abstract

The invention discloses a coal mine roadway temporary reinforcement and support device in coal mine mining and driving, which comprises a coal mine roadway main body, a base, a mounting block, a connecting block and a pressure sensor. A mounting block is connected, and a connecting block is arranged above the mounting block, a connecting column is arranged above the connecting block, and a bottom plate is inlaid on the upper end of the connecting column, and a hydraulic rod is installed on the upper surface of the bottom plate, and the hydraulic rod The upper end is connected with a support plate, and the upper surface of the support plate is inlaid with a support column. The temporary reinforcement and support device of the coal mine roadway in the coal mine mining and excavation is equipped with a limit rod and a connecting groove, and the operation panel can be fixed through the cooperation of the limit rod and the connecting groove, so that the extension of the subsequent movable plate can be kept fixed, and at the same time Subsequently, the connection between the limit rod and the connecting groove can be released by rotating the limit rod, so that the movable shaft can be controlled through the operation panel.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a temporary reinforcement and support device for coal mine roadway during coal mine mining and driving. Background technique [0002] As an important energy material, coal mines are widely used in industrial production and other fields. Since coal mines are generally hidden underground, the mining operations of coal mines are also underground operations. When mining coal mines underground, materials are generally collected by means of coal mine roadways. The stability of the coal mine roadway is related to the safety of mining for transportation and personnel entry and exit. After the roadway is excavated, it needs to be reinforced by the enclosure structure to ensure the stability of the roadway. Before the construction of the support structure, it can be temporarily supported. The device improves the support for the roadway, and it can be removed after the subsequent s...
