CONCLUSION about confirmation of the productionMobile drilling rig UBP-30
LLC Concern "Inmash" has developed a mobile drilling rig UBP-30, which provides an increase in productivity, efficiency and safety of exploration drilling, including uranium deposits.
UBP-30 is designed for drilling medium and deep exploration wells (prospecting and appraisal, exploration and drilling of artesian wells for water production) by rotary method in soft and medium hard rocks with direct (or reverse) bottomhole flushing. The installation provides high safety of work and is allowed to be used at hazardous production facilities, including in the nuclear industry for drilling wells. In a reduced configuration, the UBP-30 unit should provide drilling of wells for agricultural and industrial water supply and dewatering.
The novelty of the UBP-30 drilling rig being created consists in the use of technical solutions that allow to: reduce operating material costs (cost of ownership); to increase labor productivity, drilling speed; to increase the reliability and safety of the production process of drilling, to prevent the possibility of injury; reduce the amount of assembly and disassembly work when preparing the rig for drilling; to increase energy and resource saving; to introduce organizational innovations; to develop control technology; to improve the environmental friendliness of production.
