鸡西矿业集团公司东海煤矿通过对薄煤层工作面设备合理配套,改革回采工艺,革新辅助设备,加强技术保障,科学组织生产等措施,在平均厚度为0.9 m的薄煤层中采用高档普采开采技术,创造了月产4.5万t、日产1800 t的记录,实现了薄煤层高产高效创水平。

Practice of Thin Coal Seam Mechanization High Output and Efficiency Mining Technology in Donghai Coal Mine

In Donghai Coal Mine of Jixi Mining Industry Group Comp.,many measures are applied,such as reforming stopping craft by thin coal seam face equipment reasonable necessary,innovating auxiliary facility,strengthening the technical ensurement,sciencing organization production and so on.High-grade general mining technology was used in the thin coal seam of the average thickness 0.9 meter,which created the records of the month yield 45 000 tons,and the daily yield 1800 tons,the thin coal seam high output and efficiency is realized.
