冲击地压危险源层次化辨识理论研究
|
摘要
采用理论分析并结合现场案例,指出冲击地压发生前存在潜在危险源,并将广义危险源概念引入冲击地压监测中,定义冲击地压能量积聚至破坏启动的区域为冲击地压危险源,进一步分析冲击地压危险源具有触发因素、潜在危险性和发展趋势3个要素,指出一切冲击地压监测的统一目标为及时、准确地辨识到冲击地压危险源。对冲击地压危险源产生的时空状态进行分析,为不产生盲区,提出对冲击地压危险源进行时空上的层次化辨识,并且建立理论应用模型,在华丰煤矿分别选用微震监测技术、地音监测技术和煤体应力监测技术,分井田范围、工作面范围和局部危险点进行全矿井冲击地压危险源辨识。实践证明该理论可提高现场监测效率、并有效指导现场对于冲击地压显现的预测。
The potential hazards existing before occurrence of rockburst is pointed out by combining the theoretical analysis and field cases.The concept of generalized hazard source is introduced into the rockburst monitoring;and the area between energy accumulation and damage initiation is defined as the hazard source of rockburst.Then through further analysis,the hazard source of rockburst has three elements,i.e.triggering element,potentially dangerous element and development trend element.The only objective of rockburst monitoring is to recognize the hazard source of rockburst in time and accurately.The spatial-temporal state when the hazard source of rockburst generates is analyzed.In order to avoid the generation of blind area,the hierarchical recognition of hazard source of rockburst in spatial-temporal state is proposed;and the application model is established.According to the coal mine field,coal face field and local area,the hierarchical recognition of hazard source of rockburst in Huafeng coal mine,China,is conducted by using monitoring technologies of microseisms,acoustic emission and mining-induced stress.Practice in Huafeng coal mine proves that the hierarchical recognition theory of hazard source of rockburst can not only improve the field monitoring efficiency,but also guide the rockburst forecast effectively.
