Old Coal Mining Editor's Note:
The term "six long" originated in Shanxi coal mines.
This is a new invention in the large-scale merger and reorganization of Shanxi coal mines in the past three years, equipped with a full six long is a condition of access to the coal mine.
Other coal mines in the country are generally involved in the production of safety for the five mine director deputy director of personnel, that is, Henan, the so-called five mine director, that is, the mine director, chief engineer, production deputy director, deputy director of safety, mechanical and electrical deputy director.
Shanxi in the first few years of frequent mining accidents, the size of the librarians are y implicated, although greatly enriched a bit, but some librarians are also due to run the mine coal bosses big bribes and fell out of the hat and even into the classroom.
The Wang County Wang Daotai originated from the same coal gas staff, have done ventilation district captain, presided over the Shanxi Province, after the work of floating, because the ventilation safety is indeed the top priority of the coal mines, coupled with the origins of the coal mines, ventilation preference, so it is coupled with a long that is the so-called ventilation assistant mine director (generally is the part-time captain of the ventilation district), through the legal process to be implemented in the province.
Wang Daotai's move allowed ventilation district captains to take advantage of the yellow robe, forced into the class or vice president level of the quasi-class, giving them increased income. Many ventilators are still grateful to Wang Daotai!
The place called Shangpang, a few years ago, there is a jataka county magistrate into the Shangpang, and then a new creation and promotion, transformed into seven long, plus a safety production command center (in fact, it is the scheduling room) for the Shangpang County essential conditions. Jatang county guard engaged in the fancy new, and let the Shangdang County out of the color again!
Six long, seven long surface is a change of position, screw a very exciting, in fact, but is just the system inside the fried rice. When the right person arbitrarily pat on the head of a thing, so that a lot of coal people from then on the stage, increase income, shameful face into the vice president of the post above. Woohoo, in a word, unknown.
A small report in May 2012:
As the coal resource integration work in Shanxi Province wraps up, more than 1,000 coal mines are in urgent need of unified standards to regulate management. Recently, Shanxi Province, the coal industry quite introduced "Shanxi Province, coal mine modernization mine standards", "Shanxi Province, coal mine mining enterprise standards", "Shanxi Province, coal mine management standards", "Shanxi Province, coal mine construction construction management standards", "Shanxi Province, coal mine construction standards" and other five standards, to further improve the province's coal mine construction and management level, and to promote the coal industry towards "seven high and one civilization "The new standards will be implemented from the date of issuance. The new standards have been implemented since the date of issuance.
