Research and Application of New Technique for Fully Mechanized Excavation Construction of Pump Room in Mining Area
A series of construction methods and techniques are improved to solve the difficult problem of comprehensive mechanization excavation construction of pump room in mining area.Firstly,the cross-section of the pump room in the mining area is optimized,the size of the roof breaking is reduced under the condiction of ensuring the roadway cross-section meets the usage requirements,in order to adapt to the maximum cutting height of the fully mechanized excavation machine;Secondly,the right-angle turning range of the pump room in the mining area is designed to ensure that the comprehensive mechanization excavation equipment can smoothly enter the multi turn roadway for normal construction;Once again,during the construction process,phased optimization of support parameters is carried out at the right-angle turning place of the mining area pump room,avoiding waste of support materials and ensuring the reliability and safety of support;Finally,a step-by-step moving technology scheme for the dust removal fan is designed,which reduces the number of moving times of the dust removal fan during the construction of the pump room in the mining area,ensures the dust removal effect,and accelerates the construction process of the roadway.Through systematic research,the bottleneck of fully machanized excavation construction technology for pump rooms in mining areas is broken.Comprehensive mechanization excavation replaces traditional blasting excavation,promoting safe and efficient mining in mines,and generating good economic and social benefits.
