摘　　要：通过对安徽池州马头矿区含矿裂隙的综合研究,进一步认识斑岩型钼矿的含矿裂隙规律,解决此类含矿裂隙发育复杂矿区的矿体对应连接问题,有效指导矿区找矿。通过野外统计、室内数据整理及综合分析,在马头矿区选取代表性钻孔6个、平硐1个及地表露头3个,进行含矿岩体及其围岩节理裂隙特征的统计分析,开展钼矿床含矿裂隙规律研究。对矿区岩体与围岩中的节理裂隙、石英脉、钾长石英脉、断裂破碎带特征进行统计分析,发现矿区岩体与围岩中的节理裂隙特征基本一致,主要节理裂隙有5组,主要矿体含矿优势节理裂隙走向NNE,倾向SE,倾角在40°左右。Based on a comprehensive study of ore-bearing fissures in Matou mining area,Chizhou,Anhui,the law of ore-bearing fissures in the porphyry molybdenum deposit is further recognized,and this paper attempts to solve the corresponding connection problem of ore body in this kind of mining area with complex fissure development,so as to effectively guide the prospecting in the mining area.The research mainly used the field statistics and comprehensive analysis of indoor data.In Matou mining area,6 representative boreholes,1 footrill and 3 outcrops were selected to carry out a statistical analysis of the characteristics of joint fissures in ore-bearing rock mass and the surrounding rock,and to study the law of ore-bearing fissures in molybdenum deposit.The characteristics of joint fissures,quartz veins,k-feldspar veins and fissure zones in the rock mass and the surrounding rock in the mining area were statistically analyzed.It is found that the characteristics of joint fissures in the rock mass and the surrounding rock in the mining area are basically consistent,and there are 5 groups of main joint fissures.The predominant ore-bearing joint fissure of the main body strikes NNE and dips SE,and the dip angle is mainly about 40°.
