Name of Equipment:

Blind Shafts Drilling Complex with reverse circulation

Shaft Diameter:

Up to 10 meter

Purpose:

Complex is used to construct air and transport shafts, passageways, waste ways and pressure wells of big diameter in shafts without underground access

Benefits:

• Most safe, quick and flexible method to get access to underground chambers or air shafts boring
• No blast materials used
• Ideal for unconsolidated rocks as well as water bearing geological formations
• No need to personnel presence in the shaft during the drilling operations
• During continuous drilling, boring can achieve 20 meter per da
