基于因子分析的千米深孔地面预注浆止浆施工影响因素分析

Influencing Factors Analysis of Ground Pre-grouting and Stopping Slurry in Kilometer Deep Hole Based on Factor Analysis

摘要: 影响千米深孔地面预注浆止浆施工的因素复杂多样，诸多影响因素决定了止浆施工的成功率，运用因子分析方法对影响止浆施工的因素进行深入分析，归纳为3个公共因子:地质因素(F₁)、注浆参数影响因素(F₂)、止浆目标因素(F₃)，揭示了止浆施工过程中的影响因素综合作用的动态变化机理。通过对亳州煤业信湖煤矿主井地面预注浆工程施工案例分析，验证了因子分析方法的可行性。

Abstract: The effect factors in the process of kilometer deep hole ground pre-grouting construction were analyzed in consideration of the diversity and complexity of stopping slurry construction by utilizing the method of factor analysis. Three public factors including geological factor (F₁), grouting parameters influencing factor (F₂) and stopping slurry targets factor (F₃) on behalf of the success rate in stopping slurry construction were extracted. As a case, the analysis of ground pre-grouting construction in Xinhu Coal Mine was carried out for Bozhou Coal, in which the feasibility of the proposed method was verified by utilizing the method of Factor Analysis.
