随着煤炭经济的发展，高产高效是每个煤炭企业面临的首要问题，而提高矿井单进能力可以有效降低煤矿成本。在煤矿掘进施工过程中，下山掘进施工是不可避免的一种情况。当巷道顶板淋水较大时，会使现场作业环境变得恶劣，为掘进施工带来诸多困难。所以，在下山施工过程中，处理顶板淋水问题是其面临的首要难题。山西金晖隆泰煤业有限公司通过改变掘进工作面临时支护方式，有效地解决了顶板淋水对掘进施工的影响，为其他煤矿同等条件下支护提供了宝贵的经验。

With the development of coal economy, high yield and high efficiency is the primary problem facing each of coal enterprises, and improve the mine single ability can effectively reduce the cost of coal mines. In the process of coal roadway construction, down the tunneling construction is an inevitable. When the tunnel roof water spraying is large, will make the field operation environment became bad, it brings many difficulties for the tunneling construction. So, on the way down in the process of construction, processing of roof water drenching the problem is the most difficult problem which it faces. Shanxi Jinhui Longtai coal limited company by changing the tunnelling face supporting way, and effectively solve the impact of water drenching roof of roadway construction, for other coal mine under the same conditions support provides valuable experience.
