摘要
为了提供可靠的基础技术数据用于回采巷道支护技术研究,根据2号煤层赋存情况,进行了科学的煤层地应力测站布置,使用SYY-56型小孔径水压致裂地应力测量装置对2号煤层地应力进行了测量,得出了地应力的大小和方向。
In order to provide reliable technical data for the basis of extraction roadway supporting technology research, according to No.2 coal seam occurrence situation,has carried on the science of coal seam ground stress station layout, use SYY -56 small aperture hydraulic fracturing in -situ stress measurement device for no.2 coal seam in -situ stress measurement,the size and direction of in -situ stress is obtained.
