“There is no need to climb up to seal the upper corner of the inlet and return air of the fully mechanized m88 register mine，The wind flow adjustment of the double-lane excavation working face has been speeded up and upgraded..."
Recently，Hanjiawan m88 register Company has equipped the underground mining working face with an air bag type rapid sealing device，Received unanimous praise from front-line mining workers。
Previous，When the entry and return wind corners of the fully mechanized m88 register mining face need to be blocked，All are built with sandbags，The amount of sand is larger、Heavy workload，And employees are required to work at heights，There is a security risk。During double-lane excavation of the excavation working face，After the entry and return air contact lane is connected，To prevent wind short circuit，Adopt measures to build temporary wind barriers，But the wind barrier has poor plasticity，There is a phenomenon of air leakage in the tunnel due to deformation due to wind pressure，Easy to cause ventilation system disorder。
For this，Hanjiawan m88 register Company arranges professional and technical personnel to go out for benchmarking、Technical exchange，Introduced "YHQM air bag type rapid sealing device" for mining working faces。
The air bag device is made of flame retardant、Anti-static material composition，Contains support frame，Comply with the provisions of "General Experimental Methods and Determination Rules for Flame Retardant and Antistatic Properties of Polymer Products Used in Underground m88 register Mines"，Light weight、Easy to carry，Simple and quick operation，Can be directly inflated using underground air pressure system。Inflation time only takes 5-10 minutes，Maintain no leakage for more than 360h after inflation，Enclosed and solidly constructed、persistent，Good blocking effect，Low air leakage rate，And no wearing and consumable parts，Can be used repeatedly。
“Easy to operate，Good effect，Working becomes more worry-free，We all affectionately call it ‘Pink Dun Dun’。" Li Hongqing, leader of the electromechanical maintenance team of the continuous mining team, praised。
Due to the strong adaptability of this device to the shape of the tunnel，Can be big or small，Full of plasticity and versatility，Available in different cross-sectional shapes、Used in tunnels with different bracket forms，has become a major "sharp weapon" for the company's rescue squadron in emergency rescue work。This device can be used in complex underground tunnel environments with pipelines，Used for underground gas treatment、Isolation of carbon monoxide and dust，It can also prevent flying gangue，Promote the daily practice and combat readiness of ambulance team members。
As understood，After the device is put into operation，Enclosed construction efficiency increased by 60%，Wind flow blocking efficiency is 3 to 5 times higher than temporary wind barriers，Saving costs about 350,000 yuan。While improving the efficiency of front-line mining workers，Increased work site safety factor，Effectively promotes safe production in mines。(Author: Li Jintao Editor: Wang Yu)
