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 one of the conditions for access to coal mines. In other coal mines across the country generally involved in safety production for five mine manager deputy mine manager personnel, that is, Henan, the so-called five mine manager, that is, the mine manager, chief engineer, production deputy mine manager, safety deputy mine manager, mechanical and electrical deputy mine manager. Shanxi a few years ago, frequent mining accidents, the size of the librarians are y implicated, although greatly enriched a bit, but some librarians are also due to the mine and coal bosses big bribes and fell off the hat and even into the classroom. That Wang County Wang Daotai originated with the coal gas, ventilation district captain, presided over the Shanxi Province, after the work of the float, because ventilation safety is indeed the top priority of the coal mine, coupled with the origins of the coal mine, ventilation preference, so that plus a long that is the so-called ventilation mine assistant (generally is the part-time captain of the ventilation district), through the legal process to be implemented in the province. Wang Daotai's move to let the ventilation district captain to take the opportunity to yellow robe, forced into the class or vice president level of the quasi-class, to give them an increase in income. Many ventilation people 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 must have conditions. The fancy new thing that the county governor of Jatan engaged in made Shangdang County colorful again! The sixth and seventh chiefs are ostensibly a change of position, and it's exciting to get into a mess, but in fact it's nothing more than a stir-fry inside the system. When the right person arbitrarily patted 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 nutshell, do not know. 2012 May a small report: With the Shanxi Province coal resources integration work to close, more than 1,000 coal mines urgently need to standardize the standardization of management.
