摘要
以王坪煤电公司煤矿采区工作面为例,对顶煤垮落的过程进行了分析,并归纳了综采低位放顶煤顶板来压的特点,并对放顶煤工作面顶板来压进行计算。观测和总结了王坪煤电公司煤矿综放面顶板活动,并准确地预测及评估了工作面周期来压。为确保工作面能够有序、安全地生产,结束工作面时应确保其不受顶板来压影响。
With the working face in mining area of Wangping Coal Electrycity Company as an example, analyzes the process of top coal caving, summarizes the characteristics of roof weighting of fully mechanized low top coal caving, and calculates the roof weighting at top coal caving face. Observes and summarizes the roof movement at fully mechanized caving face of Wangping Electrycity Company, predicts and assesses the periodic weighting of working face accurately. To ensure the order and safe production of the working face, it should be ensured that the working face it is unaffected by the the roof weighting when it is ended.
