深井高地应力长工作面快速铺网刷扩技术

Rapid Net-laying and Brush-expanding Technology for Long Working Face with High In-situ Stress in Deep Mine

深井长工作面地压大,两巷及切眼变形快,传统的工作面铺网、撤架通道刷扩施工进度慢,致使深井工作面在动压影响区域停采时间长,出现“前掘后修”现象,给工作面瓦斯治理及防灭火工作带来极大难度。121304工作面采取合理控制采高、加强两巷支护及综合机械化扫底等措施,确保了工作面安全快速铺网和撤架通道刷扩工作顺利进行。

Absrtact:The deep buried pressure of long working face in deep mine is high,the deformation of two roadways and cutting holes is fast,and the construction progress of the traditional working face is slow,which results in the long stopping time of mining in the area affected by dynamic pressure,and the phenomenon of"pre-excavation and post-repair",which also brings great difficulty to gas control and fire prevention and extinguishing in the working face.In 121304 working face,measures such as reasonable control of mining height,strengthening support of two roadways and comprehensive mechanized bottom sweeping were adopted to ensure safe and rapid netting and brushing expansion of dismantling passages.
