【摘要】：為了準(zhǔn)確掌握深部巖體鉆孔的偏斜情況。采用現(xiàn)場測試和理論分析的方法,以新疆伽師銅礦項目為依托,借助EXCEL編輯校正平均角法公式,處理現(xiàn)場實測數(shù)據(jù),利用CAD繪制鉆孔傾斜平面圖及縱斷面透視圖,分析深部鉆孔質(zhì)量并提出相應(yīng)的對策。研究表明:現(xiàn)場采用KXP-2D小孔徑羅盤測斜儀進(jìn)行鉆孔測斜,可測得較為準(zhǔn)確的數(shù)據(jù)。由于礦體自身穩(wěn)定性差,鉆孔深度較深,導(dǎo)致鉆孔偏斜角度較大,且鉆孔偏斜角隨著鉆孔深度的增加不斷增大,鉆孔深度超過25m,鉆孔底部出現(xiàn)塌孔的現(xiàn)象,其中5排和6排的鉆孔鉆進(jìn)圍巖中,影響鉆孔的質(zhì)量。因此,對于鉆孔鉆進(jìn)圍巖的礦體,按照潛孔鑿巖爆破法開采,對于在礦體內(nèi)的鉆孔采用VCR法,以滿足采礦過程中安全性和經(jīng)濟(jì)性的要求。
[Abstract]:In order to accurately understand the deflection of deep rock drilling. Based on the project of Jiashi Copper Mine in Xinjiang, this paper adopts the method of field test and theoretical analysis, with the help of EXCEL to edit the formula of correction average angle, to deal with the field measured data, and to use CAD to draw the borehole inclined plane map and the vertical section perspective view. The quality of deep drilling is analyzed and the corresponding countermeasures are put forward. The results show that the KXP-2D small aperture compass inclinometer can be used to measure the deviation of borehole and obtain more accurate data. Because of the poor stability of the orebody itself and the deep depth of the borehole, the borehole deflection angle is larger, and the borehole deflection angle increases with the increase of the borehole depth, the borehole depth exceeds 25m, and the hole collapses at the bottom of the borehole. Among them, 5 rows and 6 rows of boreholes are drilled into surrounding rock, which affects the quality of drilling. Therefore, in order to meet the requirements of safety and economy in mining process, VCR method is used for drilling in the surrounding rock, and for drilling in the body of the mine, according to the method of downhole drilling and blasting.
