摘要
文章研究了不同基岩厚度上限开采综放采场矿压显现规律,确定了合理的综放工作面开采上限,将基岩厚度降低到最小33 m,通过限厚开采,确保了水体下综放开采条件煤炭资源的安全回收,从而最大限度地提高了资源回收率,减少了煤炭资源损失,对煤炭资源的安全高效开采具有重要的理论价值和现实意义。
Strata behaviors law was studied in ascending mining in fully mechanized caving face on the different thickness and reasonable mining upper limit was determined in this paper.The bedrock thickness decreases to 33m and ensure safety coal mining for fully mechanized caving under conditions of water body by mining thick limit.Thus,the resources recovery rate is improved in the maximum degree and the loss of coal resources is reduced.It has important theoretical value and practical significance for safe and efficient mining of coal resources.
