In order to ensure the safety of mining work, improve mining efficiency and rece mining cost, various economic and technical reasonable engineering measures are adopted to eliminate or control various water sources that flow into the roadway or threaten the safety of mining work, which are collectively referred to as drainage and water control work of deposit. These methods are as follows:
(1) waterproof method: refers to all kinds of methods to rece and prevent atmospheric precipitation, surface water and groundwater from flowing into the mining area. The commonly used waterproof methods include: constructing water interception and drainage engineering to intercept precipitation outside the mining area, surface water and shallow phreatic water flowing into the mining area; The diversion of surface water flow in the recharge mine; Construction of riverbed anti-seepage cushion; Filling and plugging surface water into various karst caves, ground collapse funnel, etc
(2) dewatering engineering: it refers to the method of dewatering or depressurizing the water filling source of the deposit to ensure safe mining, including the method of pre dewatering the water filling source before mining and the method of parallel dewatering, water exploration and drainage simultaneously with mining. The pre dewatering method is mostly used in large water deposits with complex hydrogeological conditions. Parallel dewatering can be carried out from beginning to end in the mining area with simple hydrogeological conditions; It can also be the dewatering work that continues to be carried out underground after the purpose of pre dewatering is achieved. In order to ensure the safety of mining work, the advance water detection and drainage work should be carried out before the roadway enters the strong water filling source or the dangerous section with water inrush
(3) underground anti-seepage method: the anti-seepage method refers to the underground engineering measures to block the water inflow source outside the mining area or roadway. At the same time, the seepage control method also achieves the purpose of protecting the water supply source, geological ecological environment and spring scenery. Measures such as setting up safety pillars and building waterproof gates (walls) in the underground also belong to this kind of method The essence of anti-seepage method is to construct underground grouting curtain on the main water filling channel of the mine by drilling grouting method. For the permeable "skylight" in the mining area, the strong water filling fault zone passing through the roadway, the water inrush of the flooded roadway and the extra large water inrush point, the local water plugging method can also be used to isolate the water source, greatly rece the water inflow or restore the proction of the flooded mine. Although this kind of waterproof project has a large investment, a large amount of work and a long construction period, as long as the hydrogeological conditions are suitable, it will receive significant water resistance and long-term economic benefits. At the same time, it can also strengthen the water resistance of the roof and floor of the mine and enhance the water resistance and compression resistance of the fault zone or safety pillar; In deep drainage mining area, it plays a al role of mine drainage and water supply source protection. In this regard, there are many successful examples at home and abroad⊙

) ah! Anqing has no bus to Gushi. You can transfer from Hefei to Gushi. Because men's tickets are from Anqing, they always go like this
at Lu'an south bus station next to Lu'an railway station, take the bus from Lu'an to Xinyang, stop at Gushi, and the ticket price to Gushi is 40 yuan
you can also take Yeji bus, and then transfer from Yeji<
Lu'an railway station has a direct train to Gushi:

it is preset by Photoshop. You can record and add new actions without downloading it separately
in the Chinese version of Photoshop, it's called & quot; Frame. ATN & quot
loading steps:
1. First call up the action panel: window display action
2. Loading & quot; Frame & quot; Action set: click the small circle button with arrow in the upper right corner of the action panel (below the close button) to display the menu
3; Frame. ATN & quot; Load the frame action to the action panel
4. When using, pay attention to remove the small tick in front of the action command you don't want to apply (such as the fixed default action and the action not used in the frame set)
if you are not familiar with the action, you'd better not play the action (open the action to see the detailed steps for more inspiration) and the creativity is more free. Generally speaking, the action is only for simple batch processing
