煤的孔隙特性研究现状及发展趋势

Research Status and Development Trend of Pore Characteristics of Coal

针对现存煤的孔隙测试手段繁多,分类标准不统一,通过总结煤的孔隙测试手段及各方法的优势和局限性,对煤的孔隙特性进行研究。分析表明,单一手段无法全面表征煤的孔隙特性,多种方法相结合可以更好地研究煤的孔隙特性,建立全尺度的孔隙测量体系,智能化孔隙探测,重塑精准孔隙模型,进而得到全面的孔隙连通性评价体系,是未来孔隙特性研究的趋势。

In view of the existing coal pore testing methods are numerous and the classification standards are not uniform, the pore characteristics of coal are studied by summarizing the pore testing methods and the advantages and limitations of each method. The analysis shows that a single method cannot fully characterize the pore characteristics of coal, and the combination of various methods can better study the pore characteristics of coal, establish a full-scale pore measurement system,intelligently detect pores, reshape a precise pore model, and then obtain a comprehensive pore connectivity evaluation system, which is the trend of future pore characteristics research.
