Problems solved by technology

[0003] Most of the support columns used in the existing roadway support lack shock-absorbing devices. For the shock generated by the mechanical equipment or the foundation soil in the mine, it is easy to cause the support of the support columns to shift, which is not conducive to stable support. Secondly, the current Some supporting safety columns lack life-saving protection devices, and cannot provide miners with effective self-rescue equipment when the roadway collapses, increasing losses

Embodiment 1

[0026] Such as Figure 1-Figure 4 As shown, a multifunctional support safety column for a mining roadway, including a safety column 3, a safety door 13 and a replacement hydraulic rod 4, a safety door 13 is provided on the peripheral side wall of the safety column 3, and a replacement hydraulic pressure is provided inside the top of the safety column 3. Rod 4, a connecting block 2 is arranged on the top of the replacement hydraulic rod 4, and a floating block 6 is arranged inside the connecting block 2.

[0027] In this example, the safety door 13 cannot be opened under normal conditions, and is bounced open by the detonating device in case of an emergency, and the supplementary hydraulic rod 4 is used to adjust the position of the top support structure to achieve optimal support and top tightness. The connection block 2 facilitates the installation and connection of the support structure and the support structure.

[0028] Such as Figure 1-Figure 4 As shown, the safety doo...

Abstract

The invention discloses a mining roadway multifunctional supporting safety column which comprises safety column bodies, safety doors and position supplementing hydraulic rods. The corresponding safetydoor is arranged on one side wall of the periphery of each safety column body, the position supplementing hydraulic rods are arranged in the top ends of the safety column bodies, connecting blocks are arranged at the top ends of the position supplementing hydraulic rods, and floating blocks are arranged in the connecting blocks. By arranging the connecting blocks, the floating blocks and dampingsprings, a buffering mechanism can be provided for the supporting safety column and a supporting vault, the vibration sense generated in operation machinery or soil can be buffered easily, the supporting column is prevented from shifting or loosening, and the supporting stability of the supporting column is improved; and safety air bags and first-aid kits are arranged in the safety column bodies,the safety air bags can protect surrounding miners against impact of ore after a roadway collapses, meanwhile, the first-aid kits can provide effective rescue for the miners, and personnel and property losses are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of roadway support, and in particular relates to a multifunctional support safety column for a mining roadway. Background technique [0002] Underground excavation requires a large number of roadways. The roadway support can keep the roadway smooth and the surrounding rock stable, which is of great significance to the construction and production of coal mines. The basic purpose of roadway support is to ease and reduce the movement of surrounding rock, so that the roadway section will not be excessively narrowed At the same time, it prevents the scattered and damaged surrounding rock from falling, but the effect of roadway support depends not only on the supporting force of the support itself, but also on the nature of the surrounding rock, the mechanical properties of the support (supporting force and shrinkability), and the installation of the support. The impact of a series of factors such as the density o...
