|
摘要
为系统研究薄基岩厚松散层地质条件下,大跨度工作面的矿山压力周期性变化特点,采用理论分析和现场实测的方法,利用KJ216/653数字化矿山压力监测服务平台实时监测记录支架压力变化,通过分析监测数据掌握大跨度工作面顶板矿山压力的周期性变化规律。
In order to systematically study the cyclical variation characteristics of mine pressure in long-span working face, which under the geological conditions of thin bedrock and thick alluvium, uses theoretical analysis and on-site measurement method, using KJ216/653 digital mine pressure monitoring service platform to monitor and record the pressure change of the support in real time, and master the cyclical variation law of mine pressure on the roof of the large-span work by analyzing the monitoring data.
