China's first "QMJ4260 full-section coal roadway high-efficiency tunneling machine" with fully independent intellectual property rights successfully rolled off the production line at Northern Heavy Industries Group Co., Ltd. on May 2 and will soon be delivered to users. According to reports, the full-section coal roadway high-efficiency tunneling machine is a first in China, with equipment technology at the domestic leading and internationally advanced level. Its successful development marks that Northern Heavy Industries has acquired the capability to develop world-leading coal mining equipment.

　　Compared with existing tunneling equipment, the full-section coal roadway high-efficiency tunneling machine can not only improve tunneling efficiency, effectively solve the problem of imbalance between mining and tunneling, and significantly increase coal output, but also reduce underground tunneling crews, lower the labor intensity of operators, and improve roadway quality and operational safety. The successful application of this innovative technology will change the traditional tunneling process, achieve rapid coal roadway tunneling and long-distance remote-controlled operation, and represents another technological leap in coal mine tunneling production methods.
