Description
Technical field
The invention belongs to coal mines without coal pillar mining technical field, be related to a kind of girdle gob side entry retaining lane gear cash holder.
Background technology
Rich coal resources in China, reserves are huge, and wherein coal seam of the coal seam thickness less than 1.3 meters is known as girdle, accounts for about
The 18% of national coal gross reserves, as comprehensive mining machineryization is promoted, girdle edge air gallery technology is also widelyd popularize, but
Girdle gob side entry retaining goaf keeps off cash supporting generally using wood point column supporting, with the raising of comprehensive mining machinery degree and exploits strong
Degree increases, and working face, which pushes to adopt speed, increasingly to be accelerated, and goaf gear cash supporting intensity is also increasing, and conventional wood point column gear cash is
It is inadaptable quickly to push to adopt, also it is unfavorable for operating personnel's safety.Conventional hydraulic rack structure cannot achieve girdle along empty at present
The comprehensive mechanization of the relatively low supporting height in lane is stayed to keep off cash supporting, main problem is as follows：
First, coal seam is relatively thin, but the correlation function for keeping off cash holder cannot still be reduced, and this requires how not change function
Under the premise of reduce support height, keep off cash to adapt to girdle gob side entry retaining mechanization, which does not obtain effectively for a long time
It solves；Second, it is effective to control holder front end empty top zone domain, preferably to be safeguarded to goaf top plate, ensure operation people
Member's safety.
Therefore, based on the above issues, need to design a kind of gob side entry retaining gear cash holder being suitable for girdle.
