摘要
综放工作面放煤的不同阶段顶板会形成"煤-煤"结构、"岩-矸"结构和"岩梁"结构,据此阐述了每种结构对应的支架载荷计算方法,明确了支架选型的主要依据。结合晋煤集团长平煤矿煤层实际赋存条件,应用结构模型进行支架载荷分析计算,通过与实测值相比较,验证了计算方法的准确性和可行性。
In the different stages of coal caving of fully-mechanized caving face,the roof will form ＂coal-coal＂structure,＂rock-gangue＂structure or ＂rock beam＂structure. Based on the different roof structure,the corresponding calculation method of support load was expounded and the main basis of support type selection was defined. Combined with the occurrence conditions of coal seams in Changping Coal Mine,the support load was calculated by using structure model. The accuracy and feasibility of the calculation methods was verified by comparing with the measured values.
