The first high-pressure annular down-the-hole drilling rig in China was successfully tested underground.

China's first CS100ET high-pressure annular down-the-hole drilling rig was successfully tested in the Shaoguan Fankou lead-zinc mine in Guangdong.

The reporter learned from relevant parties today that the rig combines the advantages of similar foreign products, has the characteristics of high efficiency, energy saving, high degree of mechanization and wide application range, and will be promoted in China.

The CS100ET high-pressure annular down-the-hole drilling rig is designed and produced by Hunan Nonferrous Heavy Machinery Co., Ltd. according to the characteristics of underground mining in lead and zinc mines. The rig adopts a crawler type self-propelled chassis, which is equipped with two driving modes of diesel engine and electric motor, which ensures that the drilling rig can move freely and flexibly in complex sections. The drill arm can be rotated by 360 degrees, which is especially suitable for the circular hole of mine underground mining field. The chisel. The whole machine is operated by computer control, with malfunction protection and fault alarm function.

The high-pressure annular down-the-hole drilling rig passed the test of a 120-meter working face under the Shaoguan Fankou mine in Guangdong, with its flexible operation, high precision of drilling (all-round accurate and reliable, positioning drilling), and high speed (high The pneumatic drilling operation was punched for 1.5 minutes in ten minutes) and was highly praised by the mechanical industry experts and operators.
