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。
The factors influencing the grouting construction of pre-grouting in deep hole of 1000 m are complicated and diverse. Many influencing factors determine the success rate of grouting construction. By using factor analysis method, the factors influencing the grouting construction are analyzed in depth and summarized into three common factors : The geological factors (F1), grouting parameters (F2) and grouting target factors (F3) reveal the dynamic mechanism of the combined effects of influencing factors in the process of grouting. Through the analysis of the construction case of pre-grouting in the main shaft of Xinhu Coal Mine in Bozhou Coal Industry, the feasibility of factor analysis is verified.
