Water damage is one of the five natural disasters in coal mines，Seriously affecting the safety production of coal mines。To prevent mine water damage accidents，Sunjiacha Longhua Mining Company fully considers the impact of various water damage factors on mining activities，From Management、Equipment、Start with technology，Pay close attention to the prevention and control of water damage。

Previously，Drainage drilling holes with water on the underground roof，Need to arrange special personnel evacuation regularly，Time-consuming and laborious；The water level in the goaf sealing wall cannot be accurately observed，Sometimes water cannot be drained in time。Since the installation of the KJ-402 mine hydrological monitoring system，No one is required to keep an eye on the scene，Can carry out real-time monitoring and control of mine water conditions in an all-round way，When the water level is high, the automatic monitoring and alarm system will be activated，The ground will arrange people to solve the problem according to the signal，Effortless and safe。
It is reported，Establishment of this system，Can detect abnormal M88 appwater volume at underground monitoring points in time、Dynamic changes in mine water inflow and mining area、Relationship between mining levels，Easy to grasp mine hydrogeological information，Understand the hydraulic connections between various water systems in the mining area and the dynamic changes in hydrology。Early detection of water damage hazards，Eliminate danger as soon as possible，Preventing major water damage，Plays a significant role in reducing casualties and property losses。
Regular physical examination "CT" in mines
Because the company adopts multi-seam mining，There are 8 closed old kilns in the mine field，There are many mines around it、Frequent mining activities，Laokong water poses a certain water hazard threat to mine safety。
For this，The company has specially set up a hidden disaster factor survey team headed by the mine manager，With mining range、Water accumulation in the goaf、The surface subsidence area is the focus，Visit and investigate surrounding mines one by one and exchange drawings，Know the mining trends of surrounding mines in real time，Do a solid job in preventing water damage。Cooperate with China Coal Science and Industry Group Xi’an Research Institute，Carry out ground geophysical exploration，The water richness of underground aquifer、"Delineate" the distribution range of water accumulation in the goaf，Take "CT" films of water-containing bodies in mines。At the same time，m88 casino reviewThe company introduced a thousand-meter directional drilling rig，Combined geophysical exploration "target area"，Truely "hit wherever you point"，Water damage management shifts from local to regional management。
Innovation increases mine water diversion
During trench mining at the working face，There are fish ponds and water storage pits in Cheergai ditch on the surface，In the process of evacuation，Due to the instability of the gravel layer，Borehole collapse often occurs。The company’s technical staff innovatively proposed the installation of screen tubes，Easily solved the problem of borehole collapse，Achieved water discharge volume from 0m3/h to 15m3/h，This ensures that mining at the working face is not threatened by surface water。
The underground raw coal bunker passes through the aquifer，Water seeps through the inner wall of the coal bunker all year round，As a result, coal-carrying water sometimes appears at the bottom of the coal bunker，Constructing "diversion" boreholes around the coal bunker，Successfully diverted aquifer water into the tunnel through boreholes。
The company has always been adhering to the principle of "mine drainage、Water supply、The trinity management concept of “ecological and environmental protection”，To improve the comprehensive utilization rate of mine water，The company filters through rock pores in the goaf，Realizing natural purification of mine sewage。The purified water can m88 best betting websitebe directly used for mine production、Choose water for washing，Simple treatment can be used for factory greening、dusting and watering，It not only reduces the cost of sewage treatment，Another solution to the problem of water replenishment in mines。(Author: Qi Xiaohua Editor: Wang Yu)
