On May 18, 2025, the 2025 China Guizhou International Energy Industry Expo and Trade Fair with the theme of "Innovation Leading and Empowering the Development of Rich Mines" opened at the Guiyang International Convention and Exhibition Center.

The exhibition invited advanced energy and mining technology equipment manufacturing brands at home and abroad to bring their latest products to the exhibition. Various high-precision equipment competed on the same stage, providing all-round technical support and solutions for enterprises in the upstream, midstream and downstream industrial chains of the energy industry in Guizhou and even the southwest region, helping to promote the high-quality development of my country's energy industry.

PART 01 Chasing the light and meeting the world

01 Intelligent Manufacturing

Based on the customer perspective, in order to fully demonstrate the innovative achievements in the fields of our company's grouting support and gas pipeline explosion suppression, Henan Coal Research Institute Keming Electromechanical Equipment Co., Ltd. carefully selected core products that are both mechanized, electrified, and intelligent to bring new choices for grouting and flame retardant explosion suppression in the coal mining field.

Our products have won the recognition and favor of many users for their excellent performance and reliability.

PART 02 Product Display

Pneumatic grouting pump for mining

Pneumatic grouting pump for mining is a double-cylinder double-liquid grouting pump. The suction and discharge actions of the two slurry cylinders are completely synchronized, which can realize the precise 1:1 ratio grouting of the two-component grouting raw materials and ensure the solidification time and final setting strength after the two components are mixed. It is suitable for both two-component grouting and ordinary grouting. It uses compressed air as power, does not require power supply, is inherently safe, and is especially suitable for working places with harsh conditions such as high water spray and high gas.

Special spraying machine for spraying

This equipment is suitable for narrow tunnel equipment and places with difficult material transportation in coal mines: it can also be used for spraying refractory materials in drying channels in cement plants, steel mills and other factories, and for the construction of other new spraying materials; according to the working environment and requirements, pneumatic or electric drive can be selected: small size, light weight, easy to move, reducing the labor intensity of workers and improving work efficiency; reducing dust in the workplace and protecting the physical and mental health of workers. The requirements of "reducing staff, safety, high production and increasing efficiency" in mines have been implemented.

Large-volume concrete spraying machine

This multifunctional concrete spraying machine is a special equipment for pneumatically conveying concrete in coal mine construction. The machine has a dust-proof function, which can effectively prevent spraying dust. The spraying volume can be adjusted from 2-6m³/h according to needs, and the long-distance transportation of concrete over 300 meters can be achieved. The quick-setting agent can be automatically and accurately added, and the crawler chassis automatically walks, which is convenient and fast to move. It has advanced technology. Reasonable structure, stable performance, convenient operation and maintenance, and long service life.

Roadway (bottom drum) repair machine for coal mines

The roadway (bottom drum) repair machine for coal mines is a professional roadway repair equipment developed for the deformation of the surrounding rock of old underground roadways in coal mines. It is fully hydraulically controlled, with crawler walking, remote control and manual operation modes. It has the functions of mobile crushing and excavation in coal mines, and is mainly used for bottoming, wall expansion, loading and unloading and transportation of underground roadways (especially small and medium-sized roadways) in coal mines. The equipment has the characteristics of compact structure, easy operation, large crushing force, high work efficiency, etc., and is especially suitable for narrow working spaces underground.

Automatic powder spray explosion suppression device for gas pipeline transportation

Applicable to gas extraction pipelines, exhaust pipes, and gas transportation pipelines for power generation, and has the function of suppressing flame combustion and further spread of explosion flames.

Gas pipeline water seal fire retardant and explosion relief device

Used in coal mine gas extraction system pipelines. It is a pipeline gas transportation safety guarantee device that uses water seal flame retardant and explosion relief components to release explosion pressure, prevent explosion waves or combustion flames from spreading to the air intake end pipeline, and control pipeline gas explosions within a certain range.

PART 03 On-site wind collection highlights

At the exhibition site, the Keming Mechanical and Electrical Equipment booth welcomed a large number of visitors to visit and negotiate. Exhibitors came in an endless stream, and the scene was crowded and lively. With great interest and expectation, they actively participated in the enthusiastic explanations and exchanges. Round after round of business negotiations and cooperation continued, and the scene was extremely hot.

Guizhou Energy Expo is not only a feast for the machinery industry, but also a stage for Keming Mechanical and Electrical Equipment to show its strength and lead the future. Looking to the future, Keming Mechanical and Electrical Equipment will be guided by innovation and supported by technology. Under the guidance of new quality productivity, it will promote the continuous breakthrough and innovation of green, intelligent and high-end technologies, and work with customers to jointly promote the sustainable development of the shotcrete support industry and the flame retardant and explosion suppression field, and win more praise and respect for China's smart manufacturing.
