摘要
对顶板砂岩水以净储量为主,有补给性弱、易疏干的特点,我们采取超前疏放的措施,改善了开掘施工环境、降低了对安全生产的威胁;采面我们采取"先探后放"的方法和施工泄水通道的方法,降低水位,排除了对工作面的威胁;为矿井的安全生产奠定了基础。
Roof sandstone water is mainly reserved,weak recharge,and easy drainage feature.We take preemptive water drainage measures.It improved digging construction environment,reduced the threat to safety and production.On the mining face,we first explore and then drain,construct drainage channel to lower the water level,eliminate threats to face,and lay the foundations for mine safety.
