渝企破解煤炭开采世界性难题 全国首套急倾斜薄煤层机械开采系统应用成功,提高工效3倍

本报讯 (记者 陈波 通讯员 张启兵)记者8月10日从重庆能源集团逢春煤矿获悉,我国首套急倾斜薄煤层综合机械化开采系统在该煤矿应用成功,工效提高3倍。这标志着我市煤矿破解了煤炭开采技术上的一道世界性难题。

据了解,按照煤矿生产标准,煤层倾角在45度以上属于急倾斜煤层,煤层厚度在0.7米至1.3米的属于薄煤层。在这样的倾斜度和厚度的煤层中实施机械化综合开采,一直是个世界性的难题。

为破解这一难题,2010年重庆能源集团就在逢春煤矿开始了急倾斜薄煤层综合机械化开采的科研探索。

经过7年的不懈努力,这一急倾斜薄煤层综采工艺解决了世界各产煤国一直未能解决的诸多难题,取得了“工作面三机配套参数的优化、液压支架的优化改进”等数十项新的技术改进成果,获国家专利20余项,填补了国内急倾斜薄煤层综采工艺的空白。

今年6月,急倾斜薄煤层综采设备在逢春煤矿N2721急倾斜工作面安装调试,7月正式投入生产。
