| 摘 要： | 为研究中等埋深大采高综采工作面支架工作阻力及适应性,根据支架-围岩相互作用关系,在顶板类拱结构、给定变形、限定变形、多岩梁结构4种限定条件下,对311101工作面支护强度进行了理论计算。通过支架工作阻力现场实测,进一步验证支架适应性。研究结果可为类似条件下矿井支架选型提供依据。

| Abstract: | In order to study the working resistance and adaptability of shield in fully mechanized coal face with large mining height and medium buried depth,according to interation relation of the shield and the country rock,the support strength of 311101 working face has been calculated theoretically under the four kinds of qualification conditions of roof arch,given deformation,limited deformation and multi-rock beam structure.Then the shield adaptability was verified by field measurements of the working resistance.The research results can provide the basis for the selection of mine shield under similar conditions. |
