Research on support equipment for gob-side entry retaining based on flexible formwork concrete technology
In order to realize the safe and efficient mining of the gob-side entry retaining working face,the technology,construction process and equipment of the domestic flexible formwork concrete gob-side entry retaining were analyzed.Then,combined with the key design indexes such as manufacturability,and support stability and reliability of the gob-side entry retaining,a series of supporting equipment for the gob-side entry retaining was developed.At the same time,supporting equipment such as special end support,special gangue retaining support and special unit support adapted to different environments were developed to realize the non-repeated support of the roadway roof.The monorail crane type and carrier type handling system for the unit support were studied to improve the construction safety and transportation efficiency of the gob-side entry retaining working face.The promotion and application of gob-side entry retaining technology and equipment was of great significance to improve the recovery rate of coal resources and alleviate the imbalance of mining.
