【摘要】：以巖石的巖爆傾向性出發(fā),選取了脆性巖爆指標(biāo)、Barton巖爆指標(biāo)、改進(jìn)后彈性變形能巖爆指標(biāo)和沖擊能巖爆指標(biāo)作為評(píng)價(jià)巖石巖爆傾向性的判別法則。對(duì)某深部礦山的主要巖石進(jìn)行巖爆傾向性評(píng)價(jià),并進(jìn)行了相應(yīng)的力學(xué)試驗(yàn)和計(jì)算,各巖爆指標(biāo)的判別結(jié)果之間存在差異,為了更加準(zhǔn)確、合理的對(duì)4種巖石的巖爆傾向性等級(jí)做出評(píng)價(jià),將脆性巖爆指標(biāo)判別法、Barton巖爆指標(biāo)判別法、彈性變形能巖爆指標(biāo)判別法和沖擊能巖爆指標(biāo)判別法的判別結(jié)果進(jìn)行綜合分析,得出了更加準(zhǔn)確的判別結(jié)果。
[Abstract]:Based on the tendency of rock burst, brittle rock burst index, Barton rock burst index, improved elastic deformation energy rock burst index and impact energy rock burst index are selected as the criteria for evaluating rock burst tendency. In order to be more accurate, the rockburst tendency of the main rock in a deep mine is evaluated, and the corresponding mechanical tests and calculations are carried out. There are differences between the discriminant results of each rock burst index. The classification of rock burst tendency of four kinds of rocks is evaluated reasonably. The discriminant results of brittle rock burst index, Barton rock burst index, elastic deformation energy rock burst index and impact energy rock burst index are analyzed synthetically. A more accurate result is obtained.
