Abstract:

The importance of environmental protection requirements and mud performance mainte⁃

nance in geological exploration has become increasingly prominent，making the standards for mud cleaning

treatment in uranium drilling construction more stringent.Based on the characteristics of short single-hole

construction period，high frequency of machine moving and small amount of mud treatment in uranium drill⁃

ing，a mobile mud purification equipment suitable for sandstone-type uranium drilling was developed.The

equipment adopts modular integrated design，which is mainly composed of mud collection system，desand⁃

ing system，automatic control system and so on. It integrates many traditional mud treatment equipment fa⁃

cilities and processes such as mud collection，purification and discharge，and can realize dragging and walk⁃

ing. It can effectively save personnel and materials when the machine is relocated in a short distance.The

field test proves that the equipment has achieved excellent environmental protection and economic benefits

in the drilling process of sandstone-type uranium deposits，achieved the goal of one-time slurry porous use

and zero slurry discharge，and improved the drilling quality.
