工作面120 m超前支护设备配套研究与应用

Research and Application of Equipment Matching for 120 m Advanced Support in the Mining Face

针对现有综采工作面两巷120 m超前支护设备配套难题,研究如何在不加长转载机落地段长度的情况下,实现工作面两巷120 m超前支护。论文以正通煤业公司302综放工作面运输巷和材料巷120 m超前支护设备配套为例,详细介绍了运输巷条梁式超前支架跨转载机电机和破碎机电机整体式布置、单元式超前支架与条梁式超前支架组合布置以及全部采用单元式超前支架进行120 m超前支护三种配套方案优缺点,对比分析了材料巷全部采用条梁式超前支架和全部采用单元超前支架进行120 m超前支护利弊,结合煤矿实际使用情况,给出了较为合理的120 m超前支护配套方案,为上述问题的最终解决提供参考。

Aimed at the existing problem of 120 m advance support of two roadways in the fully mechanized mining face, this paper studies how to solve the problem of 120 m advance support of two roadways in the mining face without lengthening the length of the unloading section. The paper takes the equipment matching of 120 m advanced support for the transportation roadway and material roadway in the 302 fully mechanized mining face of Zhengtong Coal Industry Company as an exam-ple, introduces in detail the advantages and disadvantages of three supporting schemes, namely, the span transfer of beam type advance hydraulic support in transport roadway, the overall ar-rangement of crushing motor, the combined arrangement of unit type advance hydraulic support and beam type advance hydraulic support, and the use of unit type advance hydraulic support for 120 m advance support. The advantages and disadvantages of adopting strip beam type advance hydraulic support and adopting unit advance support for 120 m advance support in the material roadway are compared and analyzed. Combined with the actual use of the coal mine, a more rea-sonable supporting scheme for 120 m advance support is given, which provides a reference for the final solution of the above problems.
