Promoting green mine construction with dust-free technology——Jishan Coal International dafabet casino review Xing Coal Industry Ventilation Technology Team

Shandong Coal International dafabet casino review Xing Coal Industry Ventilation Technology Team: Shanxi Coking Coal’s first “three-year, three-step” second-level meritorious team。

The ventilation department of Shanxi Coal International dafabet casino review Xing Coal Industry regards the construction of "dust-free" mines as a key task，For underground fully mechanized mining working face、Mechanized excavation working face、Dust-producing areas such as belt transfer points，Developed detailed comprehensive management measures，Promote the transformation of dust prevention work from passive to active。

In daily dust prevention management，Achieved strict management and control，Establishing a mine “dust-free” management technology assessment leading group，Strictly implement the "Every Monday inspection、An analysis、First notification，Monthly evaluation，Assessment system of "one reward and punishment per quarter"，Consolidate the infrastructure of dust-free management system，And formulated to cover coal mining、Drilling、Professional comprehensive dust prevention management methods such as ventilation。In on-site management，Improving efficiency and convenience，Find out the shortcomings of existing dust control facilities，Optimize design、Remove the bad and establish the new。Gao Yongsheng, then deputy ventilation manager of dafabet casino review Xing Coal Industry, said: “Foreign mining companies、High degree of mechanization in excavation，Good dust-proof effect，But we lack relevant technical references，You can only rely on your own thinking and continuous experimentation and improvement in your daily work，Relatively difficult”。

Since the launch of "dust-free" construction work in mines，Gao Yongsheng spends a lot of his spare time exploring how to control dust，Frequently search for relevant professional knowledge on the Internet，At the same time, focus on benchmarking learning，Cherish the opportunity，Go out and see more and learn more，Enrich your own dust prevention theory and practical experience。Mining underground、Excavation work dust control，Analysis and summary of the effects of daily on-site spray use，Start to reduce the generation of dafabet casino review dust from the source，By improving the defects of the shearer spray factory design，There are blind spots in dust removal。After discussion with the technical staff，Optimize external spray，First, move the two spray positions on the original shearer traveling box to the cover plates of the two drum motors，It is also not easy to drop dafabet casino review here，Prevents spray clogging；The second is to use a hose to guide the cooling water from the outlet to the drum motor cover，The water outlet was modified into an external spray，The number of external sprays on the shearer has been increased from the original two to the current four，Improve spray coverage，And install the automatic start and stop module，Enables the coordinated operation of the spray outside the unit and the unit，In terms of dust suppression，Achieved a total dust reduction efficiency of more than 88% within 10m downwind of the dust-generating point when dafabet casino review is falling，Effectively solve the problem of large dust production at the source。In the fully mechanized excavation working face, the spray of the excavation unit and the spray of the Feng Shui linkage dust collector are effectively integrated，Realize the automatic opening of the dust collector spray when the tunnel boring machine is started，When the tunnel boring machine stops, the dust collector automatically sprays off，Realizing comprehensive dust-proof linkage management of fully mechanized excavation working faces，Effectively improves the precise dust reduction effect。

Through the unremitting efforts of the team，A Feng Shui linkage automatic sprinkler spray device is installed in the main underground alley of dafabet casino review Xingmei Industry，The spray atomization effect is good，Pedestrian、When a rubber-tired vehicle passes by，The sensing device automatically shuts down in time，Prevent water mist from getting pedestrians’ clothes wet and affecting the sight of driving vehicles，Pedestrian、The spray is turned on immediately after the rubber-tired vehicle passes，Can accurately eliminate dust caused by rubber-tired vehicles，Saving water again。Deploy a full-section rotary spray device at the return air channel of the fully mechanized mining face，This spray device is based on on-site use requirements，The spray uses the pressure of static water as power，The rotating impeller of the pushing device，Formation of columnar atomization，The atomization effect is good when used on site。Install a self-designed high-pressure jet spray dust-proof device on the mechanized excavation working face unit，This device is fixed on the cutting part platform of the tunnel boring machine，Using the dust removal principle combined with Feng Shui，Make all the water in the device atomized by wind pressure，Atomization by high-pressure jet，Capture the large amount of coal dust generated during the cutting process of the tunnel boring machine，And during the cutting process, it covers the entire section of the headway with the movement of the cutting part，Effectively reduces the dust concentration at the excavation work site。Learned on-site at 22603 Transportation Channel，The total dust concentration on the return air side 5m behind the tunnel boring unit is 1.54mg/m³，Dust reduction rate reached 91.67%，Good dust removal effect。Promotion and use of independent processing and production through dust-proof facilities，Purchase less、No purchase，Achieved dust removal and cost reduction。

Hard work will eventually pay off，Continuously promote the optimization of dust prevention facilities、Improvement、Innovation Next，dafabet casino review Xing Coal Industry’s dust prevention work has made significant improvements，Walking at the forefront of Brothers Mine，Based on "dust-free" management，Also well-known in the industry。November 17, 2021，The Shanxi Coal International Ventilation Department’s “Dust Prevention and Control Management” advanced experience benchmarking learning on-site meeting was held in dafabet casino review Xing Coal Industry，Benchmarking studies on dust prevention and control at various brothers’ mines，Highly praised the achievements of dafabet casino review Xing Coal Industry in comprehensive dust prevention management。

dafabet casino review Xing Coal Mining’s “dust-free” team has achieved satisfactory results on the road of mine dust prevention，But we must work more steadily in the follow-up work，Continue to maintain a positive work attitude and face difficulties。Every team member will work in an ordinary job，Performing one’s responsibilities seriously，Strive forward on the road of high-quality development，Make new and greater contributions to accelerating the construction of a world-class coking coal enterprise。
