In the production process of underground coal mines, bulky horizontal drilling rigs are not only time-consuming and labor-consuming for assembly movement, but also have defects such as slow drilling speed, large drilling deviation, and failure to reach the top position. Nowadays, with the successful development of a lightweight and flexible new roadway drilling rig, the problems of this type of drilling rig will be solved.
The ZYJ 269/160 frame-type hydraulic rotary drilling rig is a new product developed by Qitaihe Kuncheng Machinery Manufacturing Co., Ltd. After it was put into trial operation, the machine was designed with novelty, compact structure and strong adaptability. Many advantages such as high safety performance were well received. Recently, this new type of roadway drilling rig has obtained national patents and successfully obtained the safety certificate for mining products issued by the State Administration of Work Safety.
