| Abstract: | By researching on and applicating the technology of dynamic pressure waterflooding in short holes, quickly moving the supports and optimizing the four- bar linkage, problems of coal wall spalling and top coal caving in the complex conditions are well solved. By researching on and applicating the technology of tilting and slippage prevention of hydraulic support, the tilting and slippage, collapsing and slanting of hydraulic sup- port are controlled efficiently. All these measures are helpful for realizing high output and efficiency of fully mechanized sublevel caving mining face. |
