Since this year，Facing the ever-changing coal market，Sunjiacha Longhua Coal Mine continues to increase the management and control of coal quality throughout the entire process，Adhere to benefit-centered、Market-oriented，Continuously optimize source management、Pay close attention to process supervision、Strengthen finished product supervision，Stick to the “lifeline” of coal quality，The key link of focusing on the "three ends"，Play the "combination punch" to improve coal quality。
Strictly control the production end，Tighten the source to control the "niu nose"。The mine insists on incremental quality improvement，In-depth implementation of the management concept of “grasping coal quality from the source”，The first step to manage coal quality，Strictly implement the "Coal Quality Management Measures"，Combined with changes in mine geological conditions，Adopt the "one policy per paragraph" approach，Carry out timely coal quality prediction and forecast，Adopt retaining top coal to control the roof，Make sure the top connection is tight，Realize the amount of gangue to be reduced as much as possible。
"Recent water discharge from the goaf area of the working face"、There is a lot of water in front of the rack，Coal machine drivers should promptly adjust the working surface to the base plate undulation，Effectively guide the direction of water flow，Concentrated drainage in low-lying water catchment areas on the floor，Resolutely put an end to the phenomenon of scrapers pulling water and coal。”Meeting before m88 casinoshift，Wang Yanhua, the leader of the comprehensive mining team, emphasized again and again。
While strengthening the control of the top and bottom plates of the working surface，Require the comprehensive mining team to increase pipe leakage、Repair quality of columns not maintaining pressure etc.，Organize and carry out special coal quality inspection and "zero point action"，For mining layout、Pioneering and Excavation、The working surface passes through faults and other weak links，Proceed irregularly、Spot checks and assessments for irregular members，Take multiple measures to control the source of production。
Strictly manage the transportation end，Keep an eye on the process control "assembly line"。The mine insists on continuously promoting the optimization of washing equipment and processes，Outstanding Coal Quality Management，Focus on strengthening the supervision of the entire transportation process，Especially for the special indicators of gangue management，Clear the impact on production time due to gangue blocking the transfer point、Heavy load start and stop indicator of belt transportation system，Safety formed、Equipment、List of quantitative assessment indicators for coal quality and other aspects，Closely link special rectification with assessment rewards and punishments，Forcing managers at all levels、Change in work style of post personnel，From top to bottom, we must truly attach great importance to our thoughts，Resolute implementation in action。
Through the implementation of a series of measures，The impact of gangue jamming at various transfer points in the mine transportation m88 casinosystem has been significantly reduced，Reduces the safety risks and labor intensity of on-site dredging operators，Effectively avoids frequent heavy-load starts of the entire line caused by jamming and shutdown of the main coal flow transportation system，Ensures equipment startup rate and regular cycle operation rate，Reduced gangue output and raw coal washing volume，Improved coal quality。
Strictly control the export end，Tighten the “exit” for coal quality standards。Improve coal quality，Process control is the key point、Dynamic compliance is the key、Customer satisfaction is the pursuit，The mine adheres to a flexible and efficient marketing strategy，Taking full advantage of the market recognition of clean coal product brands，Focus on improving lump coal rate and calorific value，Guarantee the total product quantity and market supply，On this basis，Start with the ideological education of employees，Stick to the source、Transportation、Comprehensive management of processes such as promotion、Full process monitoring，Form all members、omnidirectional、Full-process coal quality management system。
To ensure that the output coal dynamically meets the standards，The mine organizes production regularly、Scheduling and coal quality management personnel go deep into the working face site，Keep an eye on key links、Critical moment，Highlight key areas，Dynamic attention to coal quality indicators，Collect coal samples regularly，Know the ash content in time、Calorie and other related indicators，Accurate feedback of coal quality information，Timely adjustment、Distribute coal types M88 loginrequired by customers，Continuously improve the comprehensive management and control level of coal quality。
“Coal quality is the lifeline，It is a bottom line that must be adhered to in the production process，To treat others as having a cold，Our attitude towards taking medicine，Advanced prediction、Be prepared for a rainy day，Completely grasp the source control and process supervision of coal quality。”At the quarterly business analysis meeting，Wang Biqing, general manager of the company, said。（Wang Xinghua）
