Abstract
The invention discloses a non-coal pillar mining method of protective coal pillars in a coal mine, comprising the following steps: dividing working faces from bottom to up according to the depth of protective coal pillars when mining and recovering reserved protective coal pillars; firstly exploring the haulage road and the return aircourse of a first working face during mining, adopting a convention method for goaf filling while mining, and reserving the return air course by utilizing a conventional mode of protecting roadway along retained roads to serve as the haulage road and the return aircourse of the next working face; transferring to the preparations of the next working face when the first working face is mined, namely tunneling the return aircourse of the second working face; filling the recovered waste rock offscum in the goaf of the first working face in the tunneling process; and performing the operations by analogy until the whole protective coal pillars are mined. The invention needs no roadway coal pillar between two working faces, and all coal resource can be mined, thus realizing the recovery of the road coal pillars.
Description
Technical field
The present invention relates to the coal mining method, relate in particular to the exploitation method of protection coal column.
Background technology
In coal mine shaft lining exploitation, in order to protect surface structures and the facility around the shaft of vertical well, all to reserve the protection coal column, prevent surface collapse, treat that whole mine has been adopted after, will protect the coal resources of coal column to be exploited recovery again.When the resource of the coal column of exploitation protection in the past, all be that the mode of exploiting field work plane is routinely exploited, promptly be divided into several work planes, each work plane is all at the arranged beneath haulage drift, and the return aircourse is arranged in the top, also will reserve chain pillar between work plane.The deficiency of this mining type is, the one, and the roadway opening amount is big, and the 2nd, chain pillar can not reclaim, the waste resource.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing protection coal pillar mining, invent a kind of no coal pillar mining method.
For achieving the above object, the technical scheme that the present invention takes is:
The first step: when reservation protection coal pillar mining is reclaimed,, exploit, be divided into first work plane from bottom to top by job order from bottom to top according to the number that the degree of depth of protection coal column determines to exploit work plane, second work plane, the rest may be inferred;
Second step: haulage drift and the return aircourse of at first opening up first work plane during exploitation, cut coal by normal coal-mining method, adopt conventional method to carry out goaf filling while exploiting, and the mode that adopts conventional gob side entry retaining to protect the lane keeps the return aircourse, as the haulage drift and the double intake of doing of next work plane;
The 3rd step: during first working face mining, change the preparation of next work plane simultaneously over to, promptly tunnel the return aircourse of second work plane; Spoil waste residue with extraction during driving is filled in the goaf of first work plane;
The 4th step: after first work plane has been adopted, change the exploitation of second work plane over to, exploitation method is identical with first work plane, and carries out the preparation of the 3rd work plane by the 3rd step;
The 5th step: change the exploitation work of the 3rd work plane after second work plane adopted over to, and proceed, until the whole protecting coal column has been adopted by above-mentioned steps.
Good effect of the present invention is:
1, each work plane is equivalent to only tunnel a tunnel, and both as the return aircourse of a last work plane, again as the haulage drift (the double air intake lane of doing) of next one work, total driving amount significantly reduced;
2, no longer be provided with protection pillar between two work planes, but with all extraction of all coal resources;
3, the spoil waste residue that tunnels out no longer rises to ground, directly is filled in the goaf, has reduced lifting transport amount.
The specific embodiment
Those skilled in the art can implement according to the described technical scheme of summary of the invention, are not described in detail at this.
Claims (1)
1. the no coal pillar mining method of colliery protection coal column is characterized in that it may further comprise the steps:
The first step: when reservation protection coal pillar mining is reclaimed,, exploit, be divided into first work plane from bottom to top by job order from bottom to top according to the number that the degree of depth of protection coal column determines to exploit work plane, second work plane, the rest may be inferred;
Second step: haulage drift and the return aircourse of at first opening up first work plane during exploitation, cut coal by normal coal-mining method, adopt conventional method to carry out goaf filling while exploiting, and the mode that adopts conventional gob side entry retaining to protect the lane keeps the return aircourse, as the haulage drift and the double intake of doing of next work plane;
The 3rd step: during first working face mining, change the preparation of next work plane simultaneously over to, promptly tunnel the return aircourse of second work plane; Spoil waste residue with extraction during driving is filled in the goaf of first work plane;
The 4th step: after first work plane has been adopted, change the exploitation of second work plane over to, exploitation method is identical with first work plane, and carries out the preparation of the 3rd work plane by the 3rd step;
The 5th step: change the exploitation work of the 3rd work plane after second work plane adopted over to, and proceed, until the whole protecting coal column has been adopted by above-mentioned steps.
