中文摘要：
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.
英文摘要：
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 cuttings weight linearly increased before the peak ground pressure and decreased after it under the premise of drilling in strict accordance with the operating rules.Based on the theoretical analysis of ground pressure and gas pressure on the longwall mining face,a positive relation of drilling cuttings weight to ground pressure and gas pressure was deduced.The drilling cuttings weight positively changed with ground pressure at the fixed gas pressure or with gas pressure at the fixed ground pressure.
