残留矿柱回采过程中地压活动联合监测技术研究
|
摘要
残留矿柱的回采具有地质开采条件复杂,地压活动剧烈等特点,潜在的安全生产风险大。对残留矿柱及围岩体的监测是保障安全生产的有效手段,针对目前单一监测技术的局限性,提出不同监测手段联合监测的技术方案,实现各种监测指标互为印证,提高监测数据的可靠性和分析的准确性。给出了微震监测和常规应力应变监测联合监测技术在某矿山应用案例。结果表明该方法能够有效保障矿山安全生产。
Residual pillars stoping has the characteristics of complicated geological mining conditions and severe geostatic activity,which have potential risk to safety production. The monitoring of surrounding rock mass of residual pillars is an effective means to ensure safety production. The monitoring method is suggested to solve the limitations of current single monitoring technology,which can realize a variety of monitoring indicators for mutual confirmation and improve the reliability of monitoring data and the accuracy of the analysis. This paper presents a specific case of micro-seismic and routing monitoring technology in a mine. The results show that the method can effectively ensure the safe production the mine.
