煤炭工业技术的进步。可以使矿工们关于建立某种能为解除沉重的手工操作和实现无人工作面创造条件的采煤工艺的宿愿得以实现。这种采煤工艺就是采面的综合机械化。要求建立综机采面已经有30多年的历史了。但是只是在九五计划期间,才在一米以上厚度的缓斜煤层中广泛采用。 长时期内(图1),在技术进步影响下,采煤方法是各种各样的,但其中有一种是主要的。其比重增至35—65％,而后它就让位于更加先进的采煤方法。在40年代,是截煤机掏槽钻爆采煤;在1955～ Progress in coal industry technology. Miner’s dream of establishing a coal mining process that would create the conditions for lifting heavy manual operations and realizing unmanned work surfaces would be achieved. This coal mining process is the comprehensive mechanized mining face. Requires the establishment of fully mechanized mining face has been more than 30 years of history. However, it was only widely adopted in gently inclined coal seams above 1 meter in thickness during the Ninth Five-Year Plan period. Over the long term (Figure 1), coal mining methods are varied under the influence of technological advances, but one of them is major. Its share increased to 35-65%, and then it gives way to more advanced coal mining methods. In the 1940s, it was a coal cutter cut blasting blasting coal; in 1955 ~
