随着生产能力的提升,加快了综采面的接续,如何提高综采面回撤速度是实现矿井稳产、高产重要因素。哈拉沟煤矿12上101综采面作为国内首个450m超长工作面,末采期间首次利用连续性PET400×400KN/m柔性网连续支护回撤工作面,改变以往综采面的回撤使用传统的金属网人工间断性连网支护方式,提高了末采贯通回撤通道速度与质量,保证了作业安全。
With the improvement of production capacity, the continuation of fully mechanized coal mining face is accelerated. How to improve the withdrawal rate of fully mechanized coal mining face is an important factor to realize stable and high-yielding mine. As the first 450m long working face in Halagou Mine, Halagou Coal Mine is the first 450m long working face in China. For the first time, continuous retracting with flexible continuous mesh of PET400 × 400KN / m during the last mining period can withdraw the face and change the previous withdrawal of fully mechanized mining face The use of traditional metal mesh artificial intermittent networking support methods to improve the end of mining through the retractable channel speed and quality to ensure job safety.
