摘　　要：基于反射率及形态学参数建立煤岩显微组分自动识别的方法学和识别模式,可降低煤岩显微组分识别的主观性,为实现煤岩显微组分快速与准确测定提供技术支撑,以期有效促进煤岩显微组分自动识别技术的发展。对油浸反射光下煤岩显微组分的反射率特征和形态结构进行归纳,提出反射率信息的利用方法,并对均匀、突起、球形度、细胞结构等关键形态参数进行抽象描述,提出煤岩显微组分自动识别的方法;在此基础上以反射率、形态学参数(突起、细胞结构)和几何特征构建煤岩显微组分自动识别模式,提出煤岩显微组分自动识别技术的制约因素及发展方向。结果表明,以反射率和形态参数为主要参数的显微组分分类方法具有可行性,通过逐步分解分别建立单煤和混煤中显微组分的识别模式,组分识别的精度较高,制样缺陷、图像清晰度及细胞结构的划分对显微组分识别造成较大干扰。The subjectivity of macerals identification can be highly reduced by the automatic identification method and recognition pattern of macerals based on reflectance and morphological parameters,which provides technical sup-port for the rapid and accurate determination of macerals.The reflectance characteristics and morphological structure of coal macerals under oil immersion reflection light were summarized.The utilization of reflectance was proposed.The key morphological parameters such as uniformity,relief,sphericity and cell structure were abstractly described.The automatic identification method of coal macerals was proposed.Based on reflectance,morphological parameters(relief,cell structure)and geometric characteristics,the automatic recognition pattern of coal macerals was con-structed.Finally,the restricting factors and development direction of automatic identification of coal macerals were put forward.The results have shown that the classification method based on reflectance and morphological parameters is feasible.The recognition patterns of macerals in single coal and blending coal can be established by stepwise de-composition.The accuracy of maceral identification is high.The defects in sample preparation,the quality of image and the division of cell structure have great influence to the recognition of macerals.
