The first full-surface hard rock rapid boring machine in China is launched

On September 8, China's first full-surface hard rock fast boring machine, Aegis Chongqing No.1, was rolled off at Tiefa Energy.

Mr. Bao Hong, party secretary and chairman of Liaoning General Heavy Machinery Co., Ltd. introduced that traditional hard rock excavation technology has low efficiency, serious pollution, and high operating costs have been a common problem that plagues coal companies. Liaoning General Heavy Machinery Co., Ltd. follows the strategy of Tiefa Energy. Deploy, push forward the structural reform on the supply side, vigorously develop high-end coal machinery equipment, and accelerate the pace of transformation and upgrading of the company. Starting from 2014, we will develop a small TBM product suitable for hard rock excavation in high-gas mines in coal mines. Full-section hard rock rapid boring machine. After nearly two years of hard work, the company developed the KSZ-2600 "Aegis No. 1". The products have been recognized by industry experts and leaders, and have also attracted the attention of many coal companies. They have arrived in Beijing for rock tunnel excavation construction and industrial performance tests, and have also achieved the expected results.

“The complicated geological conditions in the Chongqing area and the serious gas disasters are one of the hardest-hit areas identified by the former Coal Ministry. For a long time, we have been seeking to find a solution to the rapid excavation of high gas rock roadway in coal mines.” Deputy General Manager, Chongqing Energy Group Li Wenshu said that "Aegis 1" has strengthened the determination of Chongqing Energy Group to introduce technology. In 2016, Liaoning General Heavy Machinery Co., Ltd. and Chongqing Energy Investment Group Science and Technology Co., Ltd. reached a cooperation agreement, and the two sides decided to jointly develop a full-surface hard rock rapid boring machine suitable for hard rock excavation in high-gas coal mines in the southwest region. number". For more than 300 days, "ShenDong ChongQing No. 1" has finally succeeded in getting off the line with close cooperation and joint efforts. With a diameter of 2.8 meters and a length of 17 meters, the product is the first small-diameter TBM product for mine tunneling in high-gas mines. The product has successfully integrated engineering TBM (full-surface tunnel boring machine), coal mine explosion-proof, automatic measurement and control and other advanced technologies, relying on product, process innovation, with a circular roadway once into the lane, synchronizing the tunneling work and rapid tunneling, with data wireless Transmission, remote automatic control, fault self-diagnosis, automatic status adjustment and many other intelligent features can greatly improve the working environment, reduce construction costs and labor intensity, and improve operational safety. Equipment will be widely used in coal mines, water conservancy, power, roads, railways, military, underground pipe corridors, gas transmission and non-coal mines.

Zhang Yong, chairman of the China Coal Machinery Industry Association, said that the success of the “ShenDong ChongQing No. 1” has opened the prelude to the rapid construction technology revolution of mine tunnels in high-gas mines in China, effectively promoting the informatization and industrialization of coal. The deep integration of machinery and equipment provides China's coal mining enterprises with the goal of "mechanization and substitution, automation and reduction of personnel" and scientific and technological security goals as soon as possible, providing reliable technological theoretical basis and strong equipment and technical support.
