Wishing you peace, joy and happiness through Mid Autumn Festival and the coming National Day.  Origin of Mid-Autumn Festival The Mid-Autumn Festival evolved from the story of Chang'e flying to the moon. Hou Yi shot down more than nine suns, and then God gave him the medicine to become an immortal. But he was reluctant to leave his wife Chang'e and gave the medicine to Chang'e for safekeeping. On August 15, Chang'e ate the medicine and flew to the moon. Because Hou Yi missed Chang'e very much, he would place Chang'e's favorite food in the yard every year on this day, looking forward to her coming back for reunion. Since then, it has been like this every year and has evolved into a festival for generations. Since this day is the Mid Autumn Festival, it is called the Mid-Autumn Festival. Origin of National Day In the feudal era of our country, there were no greater celebrations than the enthronement and birthday of emperors. Therefore, in ancient China, the emperor's enthronement and birthday were referred to as the "National Day". Today marks the anniversary of the establishment of the country as National Day. The National Day of the People's Republic of China is a symbol of the country, which becomes a symbol of an independent country and reflects its national and political system. Since 1950, October 1st, the great day on which the People's Republic of China was proclaimed, has been designated as the National Day of the People's Republic of China.

After the establishment of the project, the two sides have held meetings for many times to communicate deeply and determine the plan. The underground environment is complex, so the scheme design shall be carried out according to the situation of single track. The reconstruction of No. 5 monorail crane has been completed. It is mature to conduct remote driving on the well through the operation platform. Jinqiao Coal Mine Electromechanical Department organizes all work areas of the unit to carry out science popularization study Leaders from Shandong Provincial Energy Bureau, Jining Municipal Energy Bureau and Jining Energy Group visited the 5G+monorail crane project and gave high praise.

Affected by the strong cold air, there will be a strong cold wave weather process in the city recently, with the lowest temperature dropping by 12-14 ℃. In the early morning of December 1-2, the minimum temperature dropped to about - 3 ℃, and the strong cold wave process was accompanied by a gust of 7~8 There will also be a light rain weather process in our city on December 3-4. Wantai reminds you: cold wave is coming, pay attention to keeping warm! It is cold and dry in winter, which is easy to cause personal injury accidents such as frostbite, poisoning, slipping, etc., which also has a certain impact on the safety production of enterprises. How to prevent accidents? Wantai Shares will give you a call. 01 Prevent mental paralysis The weather is cold, the clothes are bloated, and people's hearing, vision, actions and emotions will be affected. It is necessary to strengthen warning education, strictly implement the safety production responsibility system, and maintain a good and stable production working state. 02 Antifreeze Low temperature may cause deformation and fracture of equipment and metal components, which may easily lead to leakage, explosion, fire and poisoning accidents. Each workshop shall do a good job in the insulation of water pipes, material pipes and air pipes to prevent the freezing of mechanical equipment from affecting production. 03 Anti slip and anti fall Scaffolds, ladders and steps on the production site are easy to freeze when encountering rain or snow, and they are easy to slip and fall when working up and down. Pay attention to timely cleaning rain or snow, and add necessary anti-skid measures. 04 Windproof Listen to the weather forecast in time to prevent the sudden attack of cold current, strong wind and other weather, and do a good job in prevention: check the hanging objects and various signs and signs at the production site. 05 Anti static It is dry and dry in winter, which is easy to generate static electricity and cause fire, explosion and personal injury accidents. It is forbidden to wear chemical fiber clothing into the unit area. Before loading the tank for sampling and other operations, touch the static elimination facilities to release static electricity. 06 Electric shock prevention Strengthen the management and production reduction of temporary lines, electrical equipment and facilities on production and operation sites, clean up the phenomenon of illegal electricity use, and focus on the inspection of devices in critical parts. 07 Poisoning prevention In cold winter, it is easy to cause the accumulation of toxic and harmful gases such as carbon monoxide. Ventilate regularly. Strengthen the inspection of air supply pipeline to prevent combustible gas from gathering indoors. 08 Fire prevention Ensure that the fire fighting facilities and equipment are complete, intact and effective, and the fire fighting access is unblocked. Do not use electric heating equipment indiscriminately and do not pull temporary l...

Recently, the "Pansidong Coal Mine 11411 Working Face Microseismic Monitoring System Project" of Huaihe Energy Holding Group Coal Industry Company undertaken by Wantai Co., Ltd. was successfully completed and successfully passed the final inspection and review. The project was evaluated by an expert team composed of the chief engineer of the coal company, the general defense geological technology department and the leaders of Paner Coal Mine. It took 9 months to construct a microseismic monitoring system in the two troughs of the 11411 face to monitor hydrogeological anomalies such as the development of the fracture weak zone of the top and bottom plates during the mining period of the 11411 face. The project started in August 2021 and the monitoring ended in May 2022, completing a total of 245 daily reports, 82 semi-daily reports, 40 weekly reports and 10 monthly reports. Through the analysis of monitoring data results, rationalization suggestions are put forward to provide guarantee for safe production in the working face. A total of 2 6-channel microseismic monitoring substations are deployed, one each for the upper and lower troughs. A total of 11 single-axis microseismic sensors are installed. · The upper groove is 1#~6#, 6 single-axis microseismic sensors. · The lower groove is 7#~11#, 5 single-axis sensors. The spacing of the microseismic sensors is about 100m, and the microseismic sensors are staggered along the direction and depth of the coal mine, and are arranged in the upper trough mining gang and the non-mining gang in the lower trough according to the actual situation underground, forming an envelope on the 11411 working face in space, and completing the monitoring of water inrush of the coal seam floor and the stability monitoring of the surrounding rock during the mining period of the entire 11411 working face. The micro-fracture signals of coal rock induced during coal seam mining were collected, the microseismic signal waveform analysis was carried out, and the hydrogeological anomalies of the coal seam floor of the 11411 working face were continuously monitored by synthesizing the spatio-temporal characteristics of microseismic events, the b value of microseismic events and CT imaging inversion. During the period, a total of 6462 effective microseismic events, 2452 bottom plates and 4010 top plates were monitored, and the energy was mainly concentrated in the range of 100J~500J. Monitoring confirmed that the coal seam floor and fault structure of the 11411 working face did not form a water channel. The microseismic monitoring system is a microseismic monitoring, identification and positioning and CT imaging algorithm independently developed by Anhui Wantai Geophysical Technology Co., Ltd., a subsidiary of Wantai Co., Ltd., and the "Wantai Microseismic Laboratory" jointly established by the University of Science and Technology of China. At present, the technology is at the international leading level. Sensor recognition of vibra...
