摘要
通过对采煤工作面的实际观测,找出了顶板管理方面的不足和不安全因素,通过在生产实践中的不断改进,以及改进后在采煤工作面实际矿压观测,提出了加强采面安全生产及支护的几点做法。
Through presses the observation to the mining coal surface oreprehhure, Have foued out the insufficent and discomposed factor that printing plate nanages, inprove by the ceasdesaness in producing practice, the ore presses on coal mining face reality observation, proposed enhancement mining coal woeking surface production safely and supports and proteections intesity several procedures.
