متن کاملExploration and Grouting of Large-Scale Water Capsule in the Fault Fracture Zone of Yonglian Tunnel
A large-scale water capsule was formed after 8 times inrush of mud and water in Yonglian tunnel. The capsule seriously inhabited the construction of the tunnel. By combining with the geological conditions in tunnel site, the causes and characteristics of the water capsule were analyzed. Its spatial location and size were explorated by comprehensive exploration methods. In order to control the w...
متن کاملSustainble Energy Solutions in Reinforcing Cement Manufacturing with Energy Efficiency
Concerns about global Climate and sustainable energy are perhaps among the most inevitable and fanatical issues of the present time. To tackle concerns arising from high energy consumption and its adverse environmental impact, in recent years has caused manufacturers to establish energy management cell and policymakers to formulate policies. These Policies and required to be firmly held, in ord...
متن کاملImage Mining for Intelligent Autonomous Coal Mining
Automation in underground mining enhances safety and leads to economic efficiencies. After more than 50 years of research, automation tasks have gradually been growing out of the classic engineering/mechanical environment and require a sophisticated datamining treatment. The success of (mechanical) process automation has left only one remaining place in the coal-excavation process where human l...
متن کاملStability of upper face height-total face height ratio with increasing age.
A number of investigators, while recognizing that vertical facial dimensions continue to increase throughout adulthood, have commented on the relative constancy of vertical facial proportions during growth. Broadbent (Angle Orthod 7: 209, 1937) claimed that a proportional increase in the size of the segments of the face occurs after deciduous dentition is completed. Brodie (Am J Orthod 26: 741,...
