【正文】 數是可行的。 (2)爆破主振頻率遠大于邊坡的自振頻率，因此邊坡不 易破壞。 (3)爆破震動持續(xù)時間一般都在 500ms以內。 (4)在地質條件一定的情況下，距離和藥量是影響爆破震動大小的主要因素，并且距離的影響較藥量敏感。 4 結論 (1)高陡邊坡的穩(wěn)定性。在高邊坡上開采掛幫礦的問題時，需根據邊坡穩(wěn)定性監(jiān)測的實際，做出目的明確符合實際的監(jiān)測設計，建立起實時監(jiān)測系統(tǒng)，確保邊坡穩(wěn)定。 (2)爆破對高陡邊坡的影響不容忽視，應對其進行減震控制，并根據現場需要，爆破震動進行實時監(jiān)測，確保安全開采。 5 (3)在邊坡變形監(jiān)測和爆破震動監(jiān)測時，應根據工程地質和需要，布置監(jiān)測點，突出重點，兼顧全面 ，確保邊坡穩(wěn)定。 6 參考文獻 ： [1] 事新基．霉天持地下開采不停產過度的探討 [J]．冶奎礦山設計與建設， 1999． [2] 孛 明．黑旺鐵礦邊角礦律聯(lián)合開采的應用 [J]．金屬礦山，2021(12)， 2O～ 23． [3] 黃石墻礦工程設計 l競有限責任公司．開采方案設計說明書[R]．武漢 ： 武漢鋼鐵集團礦業(yè)有限責任公司 . 2021． [4] 虞 玨．大墻鐵礦露天南迎坡掛幫礦開采技術的研究 [D]．武漢 ：武漢科技大學， 2021． [5] 蔡路革 . 馬建軍 ，用余圭等．巖質南邊坡穗定性變形監(jiān)洲廈應用[J]．全晨礦山， 2021(8) [6] 羅畚成．辱震對邊坡靜定性影響的研覽現狀與發(fā)展 [J]．礦業(yè)快報． 2021． 10． [7] 陳柏林．礦山邊坡爆破振動洲試與分析 [J]．礦業(yè)快報， 2021． 11． [8] 孫風采．露天礦邊坡位移監(jiān)洲數據可靠性分析口 ]．礦業(yè)快報，2021． 2． 7 High steep slope mining safety under Analysis China39。s large and mediumsized metal mines are mostly built in the last century O ~ 5 1960s. After several decades of development, at present, of 80% of the iron ore mining into the advanced stage, Some mines in the high steep slope under Deep Surface Mining [1,2]. Even those who have the Closed iron ore, In order to recover mining residue in the realm of the exposed slope of the horizon remaining ore (known as the Hanging Wall Mine), also in the high steep slope under the oremining. In high steep slope mining conditions will inevitably bring about many security problems, the textbased Daye Iron 2 hanging wall mining example, right under high steep slope mining safety issues were discussed. 1, the background Wuhan Iron East Daye Open Pit century since 2 O 7 O39。s open mountain slopes into Deep opencast mining, has been adopted to the minimum 168 m level, the slope of up to 440 m, its high for the domestic and international situation steep rare. Currently, the East has been open stope Closed, transferred to the underground mining, but its regional presence to help edge of a large number of hanging wall orebody, for the recovery of resources。 we need to help the North 2 pegged to help expand help for ore mining. 2 hanging wall of the Eagle39。s Nest ore ore mining residue toward long 6O ~ 70m, the thickness 30 ~ 50m, the entire orebody was F13 faults which crosses [3,4]. As the hanging wall ore occurrence conditions are 8 unique, in their exploitation of the mining sector has been more headache is the problem, which involves geology, mining engineering, geotechnical engineering, safety and reliability of many disciplines. Produced slope on the hanging wall ore is a strong mining act, two of the safety issues, first, under the conditions of mining rock slope retain its own stability, followed by the mining construction process of the safety of operations. Both interrelated and influence each other, only to ensure that they are safe, mining purposes can be achieved. 2, the deformation of slope safety monitoring Highsteep slope mining hanging wall during the many factors, the role of these factors, Rock may be damaged, leading to the slope deformation, the most extreme oute is the loss of slope stability, and cause landslides. Due to the slope from the deformation of
