顶煤的可放性影响因素及其分类

Assessment on Influencing Factors and the Classification Top-coal Caving

该文对影响厚煤层可放性的煤层强度、埋藏深度、裂隙发育程度、夹石层、顶板条件及煤层厚度等因素进行了分析,介绍了厚煤层的可放性分类。

The factors such as the Strength, the Depth of Burial, the Joint and Crack Feature, the Deposit Bands, the Roof Condition, and the Thickness of the top - coal that influence the caving of the coal were analyzed in this paper. Based on the influencing factors, the classification of the thick top - coal caving was given in the end of this paper.
