煤巷锚杆支护矿压监测与数据分析

Mine Roadway Bolting Pressure Monitoring and Data Analysis

通过对陈四楼煤矿21211工作面两巷道锚杆支护进行全煤巷的矿压观测,说明了同煤层的不同区段巷道处应力的差异和相同巷道应力条件下不同煤岩强度处围岩变形的差异,并定期收集整理矿压数据,对其进行分析总结,一方面可及时发现异常,采取措施,保证安全;另一方面,通过对矿压数据的持续监测分析,能够客观评价现场的加固方案是否有效,为完善与优化巷道支护设计提供重要依据。

By the full mine roadway pressure observation of Chensilou mine 21211 working face two roadway bolting support, the differences of roadway different sections at the seams and the surrounding rock deformation of different intensity of coal and roadway rock deformation under stress condition were illustrated, rock pressure data was regularly collected, with analysis and summary, on the one hand, abnormalities could be detected, with safety measures; on the other hand, through continuous monitoring of the mine pressure data analysis, which was able to objectively evaluate the scene reinforcement scheme and provided an important basis for the improvement and optimization of roadway design.
