| Abstract: | On the basis of the systematized study on typical control engineering methods and existing problems about the stability of soft rock in the coal stratum,a new idea of achieving the long term stability of clay soft rock by electrochemical modification was put forward.The basic theoretical analysis on electrochemical modifying mechanism of clay soft rock was made,and electrochemical modifying experiment was done.The experimental results showed that the electrochemical modification can reinforce clay softrock in the coal stratum under the direct current.It was suggested to use iron anchor bolt to electrochemically modify clay soft rock. |
