| 中文摘要: |
| 目前，多宝山矿田铜山铜矿深部勘查尚面临成矿后断层对矿体的切割和错动等问题，该问题严重制约着对该矿床成因的认识及深部勘查方向的选择。铜山断层是破坏铜山铜矿主矿体的主要成矿后断层，其走向为东西向，倾向南，是沿北东10°～12°方向推覆的一条压性断层。研究表明铜山断层由南向北推移的断距在东部1096勘探线为750m，西部1072勘探线断距则为1060m；由于东、西两端推应力的差异性产生东西方向的水平分力，致使断层上盘由西向东水平位移200～250m。铜山Ⅰ、Ⅱ、Ⅲ号主矿体均被铜山断层所切断，其中断层上盘Ⅰ号矿体的部分和Ⅲ号矿体的全部因被抬升已被剥蚀，本文重点讨论Ⅰ、Ⅱ号矿体在断层下盘的赋存部位。分析推测表明，铜山 Ⅰx号矿体在断层下盘赋存在1048～1084线，埋深950m以下；Ⅱx号矿体赋存在断层下盘1036～1104线，埋深1150m。通过对铜山断层下盘推测的Ⅰx、Ⅱx矿体和部分已控制的Ⅲ、Ⅴ（Ⅳ）、Ⅵ号矿体进行资源量预测，铜山铜矿总预测资源量约为铜金属390万t，预测深度为1700m。建议铜山铜矿后期勘查工作重点勘查范围界定在1048线至1096线，勘查深度在900～1700m。 |

| The Tongshan fault is a fault in the destruction of the main ore body of Tongshan copper deposit mine The fault direction is E-W，dipping into the South, overthrusting toward northeast. Offset in NS direction in the eastern prospecting line1096 is 750m ,and the prospecting line 1072 line-off distance is 1060m;because of the difference of the push force in east and west direction, a horizontal component force was produced, thus caused the hanging wall of the fault moved 200-250m from west to east horizontally.No.Ⅰ, No.Ⅱand No III main ore bodies were cut off by the fault , of which part of No 1 orebody in the hanging wall of the fault and the whole NoIII orebody have been denudated. The article mainly discussed No.I and No.2 orebody’s endowment place in the footwall of the fault. By analysis and forecasting, No.Ⅰore body is endowed the fault to footwall between the line 1048 and the line 1084,and the depth of burial is 950m. And No. Ⅱore body is endowed between the line 1036 and the line 1104, with the depth of burial of 1150m. Including the footwall of the fault ,the predicted Ix，IIx ore and the partially controlled No III、V（IV）、ＶＩorebody, the total resource amount of Cu predicted is 3.9Million tons, predicted depth is 1700m. The key exploration extent is between the Exploration Line 1048-1096, the exploration depth is between 900-1700m. |
