河北唐山市巍山长山地裂缝及其预防
|
摘要
开平煤田倒转区急倾斜煤层开采,煤层底板和覆岩向采空区滑落,波及区山体沿断层、节理、软弱结构面和软弱层面发生大规模山体裂缝。在采矿、地震和强降雨等外、内动力作用下,几十年来,山体地裂缝仍在不断发展,威胁着地下和地表人类工程经济活动安全。本文在分析地裂缝形成条件、形成机制和发展趋势基础上,提出了监测预防措施。
The exploiting of steeply slopy coal seam in inverted area of Kaiping coalfield,leads to both the coal seam floor slide and overlying strata slide to the gobs.The hills area of influence come up with huge cracks along the side of fault,joint,weak structural plane and layer.In the past decades,the hills cracks are still developing under the effect of coal expoiting,earthquake and heavy rain,these threaten the safety of human projects and economical activities both overgroud and underground.This paper will propose some monitoring and precaution measures on the base of analysis into conditions,mechanism and development tendency of cracks formation.
