“Drill when in doubt, frst drill and then tunnel”. EBZ220T cantilever road  header is designed for the unknown geological conditions or the existence of dangerous sources (water, gas, etc.) in the mining process of coal mines. lt is a kind of all-in-one digging machine that integrates the functions of tunneling and advanced drilling construction. The drilling machine carried bythis machine can effectively complete the advanced drilling constructiorwithin a certain range of the full mechanized mining face.

Technical features:

1. With the advanced drilling rig integrated into the machine body, this machine improves

the roadway adaptability of the all-in-one digging machine;

2.During tunneling, the advanced drilling rig shall return to the rear of the cutting section.

During the construction of the advanced drilling, the advanced drilling rig shall move to the front of the cutting section to realize the continuous operation of tunneling and drilling;

3.The accurate and stable drilling rig is equipped with a mobile positioning device to realize the complete mechanization of the advanced drilling construction,reduce the labor intensity of workers, and improve the safety and efficiency of the advanced drilling construction;

4. Advanced drilling only needs two people during the whole construction operation, which effectively reduces the manning;

5. The tunneling and advanced drilling construction of the roadways has hydraulic and electrical interlocking functions, with high overall operation safety.
