目前我国煤矿为实现高产、高效、低耗,一般都采用放顶煤开采工艺进行生产,但由于我国煤层赋存条件千差万别,各煤矿经济基础不一致,导致综采放顶煤支架从技术上和价格上很难达到全面推广和发展。为解决这一问题,国内各煤机生产厂家纷纷与矿校联合,开发出了一些简易支架,对推动煤矿支护产品的发展起了一定的作用。简易支架的灵活性、适
At present, coal mines in our country are generally produced by top coal caving technology in order to achieve high productivity, high efficiency and low consumption. However, due to the disparities in occurrence conditions of coal seams in our country and the inconsistent economic bases of the mines, the technical support and price Difficult to achieve a comprehensive promotion and development. In order to solve this problem, all domestic coal machine manufacturers have unite with mining schools and developed some simple supports, which play a certain role in promoting the development of coal mine support products. Simple bracket flexibility, suitable
