一、确定矿井合理的生产能力 我国煤炭技术政策对矿井井型、服务年限及水平服务年限均有所规定,并对可采储量采用了1.4～1.5的储量备用系数。经多年来的生产实践,证明这些规定基本上是合国情,切实可行的。但在生产中往往改变了原矿井设计的面貌,单纯追求高产量,忽视开拓准备。尤其在“四人帮”干扰时期,在“左”的思潮影响下,一些矿井片面追求高产量,“杀鸡取蛋”,致使一些矿井生产失调,大伤元气。扭转这种局面要用好多年的时间,造成了不可估量的损失。
First, to determine the mine’s reasonable production capacity China’s coal technology policy on the well type, service life and level of service life are provided, and the recoverable reserves of 1.4 to 1.5 reserves reserve factor. After many years of production practice, these provisions are basically proved to be in line with national conditions and practicable. But in the production often changed the face of the design of the original mine, simply the pursuit of high-yield, neglect to open up preparations. In particular, during the period of “the gang of four” intervening period, under the influence of the “leftist” ideological trend, some mines unilaterally pursued high yields and “killing chickens and taking eggs”, causing disarray in some mines and hurting their vitality. To reverse this situation will take years, causing incalculable losses.
