摘　　要：为满足西部大开发中乌鲁木齐和周边地区对建筑用石料的需求,同时也为乌市国土部门提供有效可靠的建筑用石料资源量。特对祁家沟地区进行了详细的地质勘查工作并进行了大比例尺填图,并结合疆内地质、测量、安全等多部门专家意见,通过实地测量工作绘制的地势图对该地区地势进行了合理判断,从而确定开采安全角;并对该区样品进行了岩矿鉴定和抗压性试验来确定石料的质量;根据疆内的开采条件和市场需求等方面因素,采用块段法对该地区矿区进行资源储量计算。通过上述的方法和手段,确定了45°为开采安全角,确认了该地区的安山岩和玄武岩均符合建筑用石料标准,并计算得出有效开采储量为2000万m3。In order to meet the demands of building stone in Urumqi and surroundings during the west development,but also provide effective and reliable building stone resources for the land department in Urumqi,we carried out a geological survey in detail and mapped at a large scale in Qijiagou for a very purpose with the combination of the experts＇view of geology,survey,security and other departments in Xinjiang.At the same time,we made a reasonable judgment to the terrain through the topographical map drawn by field measurements,thus we can determine the production security angle.Meanwhile,the samples were tested for the rock and mineral identification and compression so that we can determine the quality of stone in this area.According to the mining conditions and factors such as market demands in Xinjiang,we use the method of segment to calculate the ultimate resources.By taking the above methods and means,we determined the production security angle of 45°and confirmed that the andesites and basalts in this region were met the standard of the building stone.At last,we calculated the effective exploitation of reserves is2000million cubic meters.
