Coal Mine Tunnel Repair Machine: Innovative Technology Helps Efficient Operations（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will do the following on the coal mine roadway repair machine: innovative technology helps efficient operation.

In the long process of coal mining, the integrity of tunnels is crucial as they serve as key passages for coal transportation, ventilation, and personnel passage. However, due to complex geological conditions and long-term mining activities, tunnels inevitably experience deformation, damage, and other conditions. Haoyun Heavy Industry’s coal mine roadway repair machine, with a series of innovative technologies, has become a powerful weapon for solving these problems and achieving efficient operations.

1、 Innovative rock breaking technology

The traditional method of rock breaking in tunnels is often inefficient and causes significant damage to the surrounding rock mass. Nowadays, coal mine tunnel repair machines have made significant breakthroughs in rock breaking technology. The new type of coal mine roadway repair machine adopts high-frequency crushing technology, which can accurately crush the target rock and reduce disturbance to the surrounding rock mass through high-frequency and small amplitude impact. This technology not only improves rock breaking efficiency, but also better controls the crushing range, avoiding adverse effects of excessive crushing on tunnel stability.

2、 Application of Intelligent Control System

Intelligence is a major development trend in today’s coal mine roadway repair machines. The advanced intelligent control system endows the repair machine with a “smart brain”. By installing a large number of sensors in key parts of the equipment, it is possible to monitor the operating parameters of the equipment in real time, such as engine speed, oil temperature, oil pressure, and the force situation of the working device. Once an abnormality occurs in a parameter, the system will immediately issue an alarm and automatically take corresponding measures, such as reducing the equipment’s operating speed or stopping related actions, to avoid equipment damage.

3、 Integrated design and rapid assembly technology

Traditional tunnel repair equipment often has dispersed structures and requires a lot of time to assemble and debug underground, which undoubtedly affects operational efficiency. The modern coal mine roadway repair machine adopts an integrated design concept, optimizing and integrating various working modules to make the overall structure of the equipment compact and the layout reasonable.

At the same time, rapid assembly technology has been developed. The equipment is pre assembled and debugged before leaving the factory to ensure the performance and connection accuracy of each component. After arriving at the underground operation site, the equipment can be assembled and debugged in a short period of time through special connection structures and quick installation tools, and quickly put into use, greatly reducing the preparation time of the equipment and improving the timeliness of the operation.

The coal mine tunnel repair machine has made progress in rock breaking, control, material handling, and equipment structure through continuous technological innovation, providing solid support for efficient repair operations of coal mine tunnels. With the continuous development of technology, it is believed that the tunnel repair machine used by Haoyun Heavy Industry in coal mines will play a more important role in coal mine safety production, promoting the entire industry to move towards a more efficient and intelligent direction.
