摘要
井下现场实测支承压力规律参数是研究工作面超前支承压力影响范围最直观、可靠的方法。以王楼煤矿七采区27304工作面为工程研究背景，通过巷道锚杆受力监测。对27304工作面超前支承压力影响范围进行了实测研究，分析出了工作面超前支承压力影响程度及范围．对确定工作面合理停采线位置具有重要指导意义。
The parameters of the supporting pressure law in the downhole field,which is the mostintuitionistic and reliable method to study the influence range of working face leading support pressure.Taking the 27304 working face in the seventh mining area of Wanglou coal mine as engineeringresearch background. Through the stress monitoring of roadway rock bolt,study the influence range ofthe forward bearing pressure in the 27304 working face. Analysing the influence degree and range ofthe working face bearing pressure, which is of great significance to determine the position of reasonablestop-mining line in the working face.
