On the one hand, it helps to reduce the resistance of feudalization to the development of capitalist coal-mining industry, and to encourage the investment in coal-mining industry from businessmen, so there came a boom of investment in Shanxi coal-mining industry, and that promoted the prosperity of coal-mining industry.

一方面，有助于减少封建制度对资本主义矿业发展的阻力，进而鼓励商民投资矿业，此后山西出现了投资煤矿的热潮，带动了近代山西煤矿业的发展。

Supporting type is suggested to be developed into 3-prop to improve adaptability besides 2-prop and 4-prop. The difference of caving difficulty degree of coal seam is the base of caving coal method at high, medium and low position. Caving with small step and open caving flashboard used widely not only cause serious mixture of coal and rock but also hinder the improvement of top coal recovery. So we suggest caving with large step or closing caving door. Four-bar-mechanism of hydraulic support restricts development of new style caving powered support. Stabilization framework of expansion link and all-shield caving tail beam at high, medium and low position are introduced here.

支架支护型式，除了两柱、四柱以外，建议开发三柱支架以改善适应性；煤层冒放性的差异，是高位、中位和低位放煤方法存在和使用的依据；目前广泛采用的小步距放煤和开放式放煤插板不仅造成严重混矸漏矸，也妨碍顶煤回收率的进一步提高，建议采用大步距放煤和可关闭放煤口；液压支架四连杆稳定机构，制约了新型放顶煤液压支架的开发，介绍了液压支架伸缩杆稳定机构及全掩护拖移高位、中位和低位放煤尾梁。

The testing proves that it is available to ensure the working faces safety and increase the top-coal recovery that forcing blast top-coal and roof when the faces early working. The forcing blast method of the end top-coal is available, safety and reliable, it has a markedly effect to increase the recovery of the hard coal face.
