Water is generally carried out in good roadway has dug in or near roadways. The purpose is to pressure the water through physical and chemical effects, changes in the physical and mechanical properties of coal seams to reduce the impact of bias. Implementation of the high-pressure injection of coal unloading, from changing the physical and mechanical properties of coal to start, high pressure water to reach the coal unloading purposes. After the pressure of the water entering the coal flow along the weak side, played the role of fracturing and erosion, and water wedging effect of crack tip (water wedge effect) to make coal a reason to expand fissures, creating new fissures, destroyed integrity of coal, reducing the strength. It not only can eliminate or mitigate the impact of the threat of ground pressure, can also play eliminate dust, cooling, improvement of working conditions. After the seam pressure injection, after wetting the role of hydraulic fracturing and prolonged, changed the nature of coal, reduce the impact of preference, and play eliminate dust, cooling and improvement of working conditions. When the thick coal seams, coal seam roof relatively hard or hard coal by drilling or roof injection pressure to the water to make a hard roof seam or change its physical and mechanical properties become available coal or roof collapse. Water pressure on the seam or roof fracturing and softening effect mainly two aspects, including the role of the coal rock fracturing increases fissures, expansion cracks, so bedding separation, reducing the gap between the adhesive force and so on. Coal by drilling high-pressure water to make coal cracks increased moist coal can reduce the amount of coal dust mining. BZW125 / 40 coal injection pump due to inadequate environmental management capacity of small coal mines, is not strong sense of responsibility, to avoid or mitigate some intensive mining problems are more serious. BZW125 / 40 coal injection pump Currently, Shanxi coal mine gob area of ??over 5000 square kilometers, an annual increase of nearly one square kilometer area of ??subsidence; BZW125 / 40 coal injection pump also seriously undermine the extensive mining of groundwater resources, the province has 1,678 villages, 810,000 people Draught difficulties. BZW125 / 40 coal injection pump at the same time, a few loopholes, BZW125 / 40 coal injection pump through bartering and other improper means to obtain mining rights of coal resources, coal prices steadily higher stage in previous years, become riches family. BZW125 / 40 coal injection pump some coal bosses also like conspicuous consumption, leading to heated debate, BZW125 / 40 coal injection pump as in some big cities to buy real estate, fueling irrational prices rose.
