Technical Field

[0001] The utility model relates to the technical field of coal mine tunnels, in particular to a coal mine roof supporting device. Background Art

[0002] Coal mine tunnels are divided into three categories according to their service scope: development tunnels, mining tunnels, and recovery tunnels. Development tunnels are tunnels that serve the entire mine field or one or more first-level division units, recovery tunnels are tunnels that directly serve one or more recovery units, and the tunnels between these two types of tunnels are mining tunnels. This division also reflects the tunnel excavation sequence, which is consistent with the mining steps of the ore deposit. After the tunnel is developed, it needs to be supported by support devices to prevent the collapse of the coal mine tunnel.

[0003] However, the prior art still has the following problems:

[0004] Firstly, when supporting and protecting coal mine tunnels, most of the coal mine roof support devices in the prior art cannot effectively adjust the hydraulic support structure, resulting in the hydraulic support structure being unable to release force in time after being subjected to high-intensity force for a long time, thereby causing the coal mine roof support device to easily break.

[0005] Secondly, when supporting and protecting coal mine tunnels, most of the coal mine roof support devices in the prior art cannot effectively support the roof of the coal mine tunnels, and the hydraulic structure cannot effectively dissipate heat after long-term use, thereby reducing the service life of the coal mine roof support device.

[0006] In view of the above problems, the inventor proposes a coal mine roof support device to solve the above problems. Utility Model Content
