摘要
开元公司15401大采高综采工作面大倾角开采,存在设备倾倒、下滑等安全隐患问题。针对这一情况进行了开采方案的比选和论证,并制定了工作面支架安装、调整等针对性技术措施。最后实践表明,在有稳定顶板条件下,通过采取针对性的技术措施,可以有效防控支架“挤架、咬架、倒架”,15401工作面实现了安全高效开采,取得了较好的经济效益,为类似情况下的工作面开采提供了经验借鉴。
There are safety hazards such as equipment toppling and sliding in 15401 fully mechanized mining face with Large dip angle mining in Kaiyuan Company.In view of this situation,the comparison and demonstration of mining schemes were carried out,and targeted technical measures such as support installation and adjustment of working face were formulated.Finally,the practice shows that under the condition of stable roof,through the adoption of targeted technical measures,it can effectively prevent and control the support'squeezing,biting and reversing'.The 15401 working face has achieved safe and efficient mining and achieved good economic benefits,which provides experience for working face mining under similar conditions.
