| 摘 要： | 基于在重庆天府矿业有限责任公司三汇一矿2124综采工作面的现场实验,对该矿钻屑量与矿山压力、瓦斯压力的关系进行了研究.表明工作面经过钻孔卸压后的矿山压力分布规律:卸压区宽度约为5 m,5～11 m为塑性区,11～20 m为弹性区,20 m以后为原始应力区.在严格按照操作规程要求施钻的前提下,钻屑量在矿山应力峰值前呈线性增加,峰值后呈线性减少.结合长壁工作面矿山压力、瓦斯压力分布规律理论分析,推导出钻屑量与矿山压力、瓦斯压力之间存在正相关关系;在固定瓦斯压力时,钻屑量随着矿山压力正向变化;在相同矿山压力时,钻屑量随着瓦斯压力正向变化.

| Abstract: | The relation of drilling cuttings weight to ground pressure and gas pressure was investigated by in-situ experiment on the 2124 fully mechanized coal mining face of Sanhui Mine in Chongqing Tianfu Coal Industry Co.,Ltd.The distribution of ground pressure after drilling was obtained as the following: the stress-relief zone width of about 5 m,the location of the plastic zone at 5 to 11 m,the location of the elastic zone at 11 to 20 m,and the location of the original stress zone beyond 20 m.The drilling cuttin... |
