Research On Dust Removal And Purification Device For Fully Mechanized Excavation Face Of Coal Mine

Yunnan white dragon mountain coal mine,the eastern Yunnan branch mining industry is currently in construction phase,the excavation roadway as half coal rock,rock,coal lane,comprehensive tunneling machine driving.More intensive,the operator working face gas emission,The producing dust capacity is larger at the same time.The rock(coal)dust the threaten to safety production and malfunction.Comprehensive tunneling machine is as the main equipment in mine excavating production process,Comprehensive tunneling working face is process complex,and the location of the position and changeful.Both total dust concentration and respiratory rock(coal)concentration exceeds stand conditions,It consequences of rock(coal)dust explosion increasing of hidden trouble and silicosis pneumoconiosis patients.In order to solve the traditional way of dust bringing a series of problems,practice and test,this paper studies the comprehensive tunneling working face of coal mine dust purification plant.The comprehensive tunneling working face in coal mine rock(coal)for purification of dust,the dust concentration in the working face after cleansing,reached the standard of "coal mine safety rules" below.Comprehensive tunneling working face dust removal technologies adopted is as follows at home and abroad,one is the ventilation and dust removal.Dust will face through extraction ventilator emissions to return air roadway.The other electrostatic dust removal,using static and vibration fiber fence,to fell the dust.Dust removal system were reviewed at home and abroad,the comprehensive tunneling machine is presented in this paper.On the basis of research achievements of dust elimination,The removal effect,influence factors of the comprehensive tunneling working face of coal mine dust removal principle.is analyzed.The face dust removal device of dust elimination of theoretical basis and applicable condition has been studied.Through designing,production and installation,cleaning dust elimination device is applied in Bailong Hill comprehensive tunneling working face of coal mine,in line with the "coal mine safety regulations" requirements for tunneling working face dust,implement tunneling working face dust,and in removal dust elimination and efficient purpose.Through dust removing dust elimination,choosing of the drawable dust removal fan,designing the corresponding equipment and structural support,all this ensures the machine and the dust removal dust elimination system integration.After installing and using comprehensive tunneling the dust purification device of the working face,the workplaces environmental health condition is also greatly improved.Comprehensive tunneling machine moving,synchronizing dust purification devices and comprehensive.Dust purification plant sewage can be recycled.The innovation of the research is mainly comprehensive tunneling machine with purification device,a set of the vibration Xuan silk to avoid the dust accumulation,to guarantee the effect of removing dust.Increasing the three groups of 12 nozzle,injectiing to vibration Xuan silk,the effect will be enhanced By designing of random moving car,the following comprehensive tunneling machine can be moved to comprehensive tunneling machine back and forth motion.
