回采工作面刮板输送机上窜下跳原因分析及治理措施研究

Analysis of the Causes of Upward and Downward Jumping of Scraper Conveyor in Mining Face and Management Measures

针对山西煤炭运销集团某矿4317工作面采煤作业中刮板输送机存在上窜下跳现象,影响正常采煤作业,增加生产成本的问题,分析了刮板输送机出现上窜下跳的原因,结合上窜下跳的判断方法,提出相应措施。通过实际应用这些措施,有效治理了刮板输送机上窜下跳现象,每年刮板输送机故障率可降低82%、节约维修成本27.8万元,治理效果显著。

Aiming at a mine of Shanxi Coal Transportation and Marketing Group 4317 face coal mining operation scraper conveyor up and down jump phenomenon,affecting the normal coal mining operations,combined with the judgement of the up and down,focus on a number of governance scraper conveyor up and down jump phenomenon of the measures,through the practical application of these measures,effectively control the scraper conveyor up and down jump phenomenon,through the practical application of these measures,effectively control the scraper conveyor up and down jump phenomenon.Practical application of these measures,effective management of the scraper conveyor up and down phenomenon,the annual 4317 face scraper conveyor failure rate can be reduced by 82%,saving maintenance costs of 278,000 yuan,the governance effect is remarkable,and promote the mine's cost reduction and efficiency.
