"To strengthen the underground production process、Transportation process、Control and control of the washing and selection process，Eliminate the series of problems caused by the sudden increase in the amount of waste on the 213109 working face，Ensure the production system is stable and smooth。”Deputy Chief Engineer of Northern Shaanxi Mining Company、Sales Coordination Department Manager Lei Zhen said during on-site investigation。
Recent，Affected by the geological conditions of the 213109 fully mechanized mining face，Coal product quality fluctuates，Hanjiawan Coal Company adheres to problem and result orientation，Take the initiative、Precise policy implementation，Minimize the impact of changes in geological conditions on coal quality，Protect the lifeline of coal quality with all your strength。
The company m88 casinoscientifically adjusts the mining height of the fully mechanized mining face，Insist on following the machine during the boot process，Push ahead if necessary，Or take other measures to prevent roof debris from falling off。Strictly implement packaging and transportation on the excavation working surface。At the same time，Intensify underground on-site supervision，The safety supervisor on duty will report on the underground coal quality three times in one shift，Report any problems at any time。The coal quality laboratory technician at the sales center must sample and test the calorific value of coal every day，Based on coal quality sampling and testing information，Accurate、Science、Reasonable coal blending，Strive to provide coal products that meet user needs。
The Coal Quality Office organizes relevant departments to carry out special inspections and "zero-point actions" on coal quality from time to time and regularly，For underground raw coal production、Drilling、Full supervision and inspection of transportation conditions，Irregular inspection、Spot check and assessment of irregular members，Severely crack down on all types of behaviors that damage coal quality。During startup，Do not use water to wash the belt。Dust-proof spray M88 gameat each reprinting point while ensuring the atomization effect，Prevent the increase in coal moisture content caused by excessive water volume。
To strengthen the management of the washing and selection process，The coal washing plant discharges the coal slime pressed out of the concentration tank evenly every day，Prohibition of concentrated pressure discharge。Coal retaining grates are installed M88 gameat each reprinting point，Sifting through layers，Discharge debris and waste to the waste bin in a timely manner。Know the quality of raw coal in time，According to changes in raw coal quality，Adjust the screening particle size in a timely manner、Sorting Density、Coal preparation process and other production parameters，Ensure product quality after selection。Put an end to the occurrence of medium coal in the gangue，Improving clean coal recovery rate。
“After taking a series of effective measures，Currently, the calorific value of the company’s commercial coal has increased significantly，And continue to remain stable，Lump coal rate completed assessment indicators，Ensuring market development with high-quality coal products、Stable user、Improve quality and efficiency。" said Liu Yong, director of the company's sales M88 appmanagement center。(Zhou Zhufeng Li Wei)
