摘要
介绍了在复杂地质条件下,煤层厚度不稳定,且又不具备分层开采的大采高工作面技术的应用,为类似条件工作面的安全回采提供了经验。
This article introduces the application of longwall mining machine with roof supported by props against complex geology, varying coal thickness, leading to the impossibihty of being worked in slices. The experiences is provided for the similar conditions face＇s safty mining.
