摘要:

地下开采所引发的地表变形对矿山工业生产造成了严重危害,因此准确预测矿山塌陷区范围对于矿山安全生产具有重要意义。将混沌时间序列分析方法应用于矿山塌陷区范围预测中,以相空间重构理论为基础,采用小数据量算法计算得到时间序列的关键指标——最大Lyapunov指数,研究了塌陷区在相空间相点距离的演变规律,建立了塌陷区范围边界预测模型,并应用该模型对红岭铅锌矿塌陷区范围进行了分析预测。结果表明,矿山塌陷区范围变化具有混沌特性,时间序列分析方法能够很好地反映塌陷区范围的内在规律,通过计算得出红岭铅锌矿塌陷区范围时间序列的最大Lyapunov指数大于0,该矿山塌陷区范围的预测值与实际值基本吻合,误差大小不超过0.1%,验证了该方法的可靠性,为矿山塌陷区预测提供了一种新思路。

Abstract:

With the advance of mining to deep in domestic underground metal mines,surface subsidence caused by mining has seriously threatened the industrial production of the mine and the ecological environment of the mining area.Therefore,accurately predicting the extent of mine subsidence area is of great significance to mine safety production and ecological protection of mining areas.Because the mine subsidence area is a complex system,it contains various random factors,and the evolution process of the system is often accompanied by the exchange of energy,showing nonlinear characteristics.This paper demonstrates the mine subsidence area as a nonlinear dissipative dynamic system.Combined with the time series analysis method in chaos theory,the range of mine subsidence area is predicted.The specific method studied in this paper is based on the phase space reconstruction theory,and the phase space reconstruction of the deformation time series of the mine subsidence area is carried out.A small data amount algorithm is used to calculate the key index of the time series-the largest Lyapunov exponent.According to the calculation results,the chaos of the mine subsidence zone system is identified.The evolution law and energy variation law of the phase distance of the collapse zone in the phase space are studied.The prediction model of the boundary of the subsidence zone is established.The model is used to analyze and predict the subsidence zone of the Hongling lead-zinc mine.The results show that the formation and expansion of the subsidence area of the Hongling lead-zinc mine is the result of the comprehensive effects of all kinds of factors such as geological conditions,mining engineering operations and inherent nonlinear characteristics.The maximum Lyapunov exponent and associated dimension of the time series of the subsidence area of the Hongling lead-zinc mine are calculated.It is verified that the variation of the subsidence area of Hongling lead-zinc mine has chaotic characteristics.The time series analysis method can well reflect the inherent law of the range change of the subsidence area.The chaotic characteristics of the different locations in the collapsed zone are different in the phase space due to different geological conditions and mechanical properties.The established mine subsidence area prediction system can better predict the change of the subsidence area.The predicted value is basically consistent with the actual value,and the error size does not exceed 0.1%,which verifies the reliability of the method.It provides a new idea for the prediction of mine subsidence area and guides mine safety production.

Key words: underground mining, mine monitoring, chaotic time series, phase space reconstruction, Lyapunov index, surface deformation law, subsidence area prediction
