核桃峪煤矿首采面支架选型研究

Research on model selection of support on first mining face in Hetaoyu Colliery

核桃峪煤矿首采面是典型的厚煤层,通过对核桃峪煤矿首采面煤层地质条件的分析,确定了可采煤层厚度,通过理论与对比分析,确定了首采面的采煤工艺方式,采用理论计算、软件分析计算、类比分析3种方式,给出了首采面支架支护强度及工作阻力,为成套设备选型提供了科学依据。

The first mining face in Hetaoyu Colliery is a typical thick coal seam. After analyzing the geological conditions of the coal seam of the first mining face in Hetaoyu Colliery, the paper determined the thickness of minable coal seam. In addition, it determined the coal mining technology on the first mining face after theoretical and comparative analysis, and applied theoretical calculation, software analysis and analogy analysis to obtain the supporting strength and working resistance of the support on the first mining face. The research results offered scientific reference for the model selection of complete equipments.
