Face reserves improve working section recovery；
Step 4: in the case where ensuring the feasible situation of safe practice, reduce the complicated journey of working face extraction and roadway construction
The influence that residual pressure and its derivation tomography around degree, reduction after work face goaf back production construct to working face digging；
Step 5: one section of working face material lane connection roadway is open from the lane 1# Xi Zhu, the lane 2# Xi Zhu intersection, with 265.6 °~
Construct 836m~862m for 285.2 ° of orientation, after constructed 565m~578m with 335.3 °~351.2 ° orientation；
Step 6: two sections of material lane connection roadway again with 18.6 °~21.6 ° orientation construction material lane, three sections of 177m of connection roadway~
189m enters material lane after arriving F1-7 tomography.
Step 7: in material lane, one section of south 50m~60m of connection roadway arranges one section of transportation roadway connection roadway, transportation roadway connection roadway
One section of main lane opening westerly, penetrates through eastwards with the lane Xi Fu to facilitate Coal Transport, is constructed 862m with 265.6 °~277.6 ° orientation
One section of~882m transportation roadway connection roadway, after constructed two sections of 619m~630m transportation roadway connection roadway entrance with 335.3 °~364 ° orientation
Transportation roadway.
Compared with prior art, the beneficial effects of the present invention are: the corner pillar face recovery method in this kind of exploiting field, just
It recycles, has been recycled since technology, equipment limit will becoming of leaving in the corner coal column to coal mine recycling complex region
The coal resources at dead angle increase exploiting field Pillar Recovery effect, can increase the effective recoverable reserves of mine, improve coal resources, prolong
Mine service-life is grown, recycling available resources increases, and has added mine economic and social profit.
