Shanmei International Changchun Xing Coal Industry Ventilation Department takes the construction of the mine as a key work，For the working surface of the underground comprehensive mining、Comprehensive excavation working surface、Belt reprint point and other dust -producing areas，Formulated detailed dafabet casino dafabet casino comprehensive governance measures，Promoting dustproof work changes from passive to active。

In daily dust prevention management，Realized strict control of the essence，Establishing a leading group of "dust -free" management technology assessment，Strict execution "Check every Monday、Analysis、1 notice，Monthly 1st evaluation，The assessment system for one -quarter award and punishment，Infrastructure of consolidating the dust -free management system，Formulate covering coal mining、Tiger、Ventilation and other professional comprehensive dustproof management methods。In the on -site management，Realize efficiency and convenient，Find out the disadvantages of dustproof facilities，Optimized design、Revitalization。Gao Yongsheng, who was the deputy manager of Changchun Xing Coal Industry, said: "Foreign collection、High degree of digging mechanization，The dustproof effect is good，But we lack related technical reference in our hands，I can only rely on daily work to ponder and continuously test improvement，The difficulty is relatively large "。

Since the construction of the "dust -free" construction of the mine，Gao Yongsheng is exploring how to control dust，Frequent professional knowledge through the Internet，At the same time, pay attention to the benchmarking learning，dafabet review Cherish opportunities，dafabet casino Go out to see more and learn more，Rich to its own dustproof theory and practical experience。Call under the well、Digging work flood treatment，Analysis and summary of the use effect of daily spray，Top to reduce the production of coal and dust from the root，Defects from the factory design through the improvement of the coal mining machine，Dust Departure has a dead end blind area。After discussion with the technicians，Optimize the external spray，First, move the two spray positions on the original coal mining machine walking box to the cover of the two roller motors，It is not easy to drop coal blocks here，Eliminate the collapse of the spray; the second is to attract the cooling water from the exit with the rubber tube to the drum motor cover，Remove the water outlet and convert it into an outer spray，The exterior spray outside the coal mining machine has increased from two to four now，Improve spray coverage，and install the automatic start -stop module，It can make the united spray running with the crew of the united operation，In terms of dust reduction，Realized the total dust reduction efficiency within 10m of the dust production point of the dust production point when the coal drop -down point reaches 88%or more，Effectively solve the problem of large dust production at the source。Effective fusion of spray dafabet mobile login spray of excavation units dafabet casino with Feng Shui Catcher will be effectively fused in the comprehensive excavation work surface，Implementation of the dust catcher spray automatically when the excavator starts，Entrusted Port Parking, Dust Catcher Automatically Spray Turn off，Realizing comprehensive excavation working surface comprehensive dustproof joint management，Effectively improved the precise dust reduction effect。

Unremitting efforts by the team，Changchun Xing Coal Industry under the main alley of the main lanes arranged in the main alley of Feng Shui linkage automatic sprinkler spraying device，The effect of spraying atomization is good，Pedestrian、Gas wheel vehicles pass by，Sensor device automatically close in time，Preventing water mist wet pedestrian clothing and affecting driving vehicles，Pedestrian、Play wheel vehicle is sprayed immediately after passing，Can accurately eliminate the dust from the rubber wheel vehicle，Save water。Arrange the full -breaking rotating spray device at the backwind of the comprehensive mining work surface，This spray device is according to the requirements of on -site usage，Spray uses the pressure of static pressure water as power，Promoting the rotating impeller of the device，Form column -like atomization，Good atomization effect on the spot。Installed dafabet casino review the independent designed high -voltage shooting dust spray dustproof device，dafabet review This device is fixed on the platform for the excavator，The dust removal principle combined with feng shui，Makes the water of the device through the wind pressure，Obuctatization through high -voltage firing flow，Capture a large amount of coal and dust generated during the cutting of the excavator，and the full section of the headway with the movement of the cutting department during the cutting process，Effectively reduced the dust concentration of the excavation operation location。Driven at 22603 transportation slideshow，The total dust concentration of the wind side at 5m after the excavation unit is 1.54mg/m³，The dust reduction rate reaches 91.67%，Good dust removal effect。The promotion and use of autonomous processing through dustproof facilities，To buy less、No purchasing，Realized dust removal and cost reduction。

End of the hard work，is constantly promoting optimization of dustproof facilities、Improvement、Innovation，The dustproof work of Changchun Xing Coal Industry has been obviously changed，The forefront of the brothers mine，Based on "dust -free" management，It is also small in the industry。November 17, 2021，Advanced experience of the "Dust Prevention and Management" of the Ministry of Sand Coal International Ventilation dafabet review Department will be held at Changchun Xing Coal Industry，Each brothers dafabet sports betting ore on the spot for dust prevention and control learning，Give a high evaluation of the achievements of Changchun Xing Coal Industry in comprehensive dustproof management。

Changchun Xing Coal Industry "Dust -free" team has achieved satisfactory results on the road of mining dust prevention，But in subsequent jobs, it is necessary to play steadily，Continue to maintain a positive work attitude to meet the difficulties。Each player will be in ordinary jobs，Carefully fulfill your duties，Following forward on the road of high -quality development，Make new and greater contributions to accelerating the construction of a world -class coking coking coal company。
