煤层注水降尘剂性能评价及选型

Study on the Performance Evaluation and Type Selection of Coal Seam Water Injection Dust-reducing Agent

选取3类降尘剂,分别通过实验室测试,从中为长平矿4306工作面、寺河矿W2302工作面、寺河二号井97304工作面、寺河二号井1308工作面4种类型的煤样选取最为合适的降尘剂,用来改善煤层注水特性。对煤层注水降尘剂性能的评价方法及其考察结果进行了分析探讨,得出了煤层注水降尘剂的选型。

The most suitable dust-reducing agents were selected from 3 types of dust-reducing agents selected for the 4 types of coal samples of 4306 working face of Changping Coal Mine, W2302 working face of Sihe Coal Mine, 97304 working face of Sihe No.2 well and 1308 working face of Sihe No.2 well respectively through laboratory tests to improve the coal seam water injection characteristics. This paper analyzed and discussed the performance evaluation methods of coal seam water injection dust-reducing agent and the investigation results and obtained the type selection of coal seam water injection dust-reducing agent.
