千秋矿建于1956年,设计生产能力60万 t/a.1978年改扩建后生产能力增至120万 t/a。2006年随着姚四溜煤嘴系统的改造,每班可放煤2000t,运输能力的不断提高导致大巷撒煤较多。矿相关人员经过现场勘察发现,姚四溜煤嘴与矿车存在平面夹角,且溜煤嘴距离矿车中心线较远,放煤时因存在夹角。矿车内装煤靠近溜煤嘴一侧的放煤较多,若不及时处理,就会造成大巷撒煤多,影响大巷的工作环境,容易出现机车掉道事故,且需安排人员清理。费
Chiaki Mine was built in 1956 with a designed production capacity of 600,000 t / a. In 1978, it was expanded to 1.2 million t / a. In 2006, with the transformation of Yao Si slip coal mouth system, each class can put coal 2000 tons, the continuous improvement of transport capacity led to more coal mining. Relevant personnel through mine site investigation found that Yao Si slip coal mouth and the existence of plane angle, and the slip away from the center of the coal mine pipe far, there is the angle when the coal. Coals close to the side of coal miner coal charging coal more, if not promptly dealt with, it will cause the roadway more coal, affect the working environment of the roadway, prone to locomotive off the road, and the need to arrange personnel to clean up. fee
