Mining mines prone to spontaneous combustion and spontaneous combustion of coal seamsA series of fire prevention and extinguishing measures should be taken in mines that are prone to spontaneous combustion and spontaneous combustion coal seams. These measures include setting up observation stations or observation points for spontaneous combustion, arranging them in rock formations or coal seams that are not easy to spontaneously combust, adopting retreating mining, leaving no roof protection coal, etc. In addition, it was necessary to prepare a special design for mine fire prevention and extinguishing, and adopt technical means such as injecting mortar, injecting noble gas, spraying chemical inhibition agent, etc. to implement active prevention. The mine should also establish a natural combustion monitoring system to detect and discover changes in gas concentration and temperature in a timely manner, and carry out early warning and measures to improve and improve. Comprehensively consider the management of the goaf after mining, the fire prevention and extinguishing needs of the adjacent working faces and adjacent coal seams to ensure safe mining.
What kind of novel protagonist is self-combustion?I recommend " My Spirit-Killing Life in Japan ", a light novel written by a strange fan. The male protagonist, Mizugawa, was a 17-year-old high school student, and there were many other characters with different personalities. The story started from the screams in the old stadium. There were elements of spirits, like crows, black cats, and men in black helping people and spirits in the dark.
'Tokyo Landlord' was not bad either. It was a work of eight pigeons. In the daily romance genre, the male lead was Shuang Yecheng, and the female leads had their own characteristics.

The writing style was good, and the character descriptions were rich. Although there were some problems with the male protagonist and the updates were slow, the story was sweet. The recommendation index was 4 stars.

The world's earliest internal combustion engineIn 1860, the first successful commercial internal combustion engine was developed. But before that, many engineers and scientists had made promising attempts. For example, about 50 years before Renoir, the French engineers Nicepelle and Claude Nicepsey created an internal combustion engine called the Pyréolophore, which was fueled by a mixture of moss, coal dust, and resin. Francois Issac De Rivaz invented an internal combustion engine powered by hydrogen and oxygen, which used electric sparks as an ignition device and was installed on a carriage. The car became the world's first internal combustion engine car. In 1823, Samuel Brown obtained the first patent for an internal combustion engine that could be used in industrial production, namely the " gas vacuum engine." In 1826, Samuel Morey of the United States developed a non-compressed gas or steam engine with a vaporizing; in 1833, Lemuel Wellman Wright of the United Kingdom invented a tabletop double-acting gas engine with a water-jacket cylinder; in 1838, William Barnett developed what was considered the first engine to use cylinder compression. However, from a commercial success point of view, the internal combustion engine developed by Adrian Renova was the earliest.
The novel " Hundred Years of Spaceship " is equally exciting. Everyone is welcome to click and read it!
I like your story I'm just waiting for sports car and super car or hyper car and like saddest not full electric just hybrid i like to see the mc develop combustion engine
