1、xx建筑装饰材料厂建设项目可行性研究报告一、总论(一)项目概况1、项目名称:xx建筑装饰材料厂2、项目建设地址:婺源县古坦乡xx村3、项目联系人:xxx 4、联系电话:139703xxx775、合作方式:独资、合作6、项目总投资:732.34万元(二)项目建设的必要性1、满足当前市场的需求目前,国家对基础设施建设加大了力度,这其中就要用到很多的建筑装饰材料,而大理石的优越性就让消费者趋之若鹜,使大理石产品供不应求。在此基础上,建设一个建筑装饰材料厂,充分利用资源优势,生产品质较高的建筑装饰材料产品,具有较大的市场份额。2、当地经济发展的需要古坦乡位于江西省婺源县的西北边陲,东邻大鄣山乡,南连赋
2、春镇、甲路乡、清华镇,西北两面与安徽休宁和江西景德镇市瑶里镇接壤,面积117平方公里,总人口1万余人,境内山峦叠嶂,绿荫遍布。xx洞国家森林公园座落在该乡境内,是典型的革命老区和贫困乡。为了改变老区经济的落后面貌,拟对该乡水岚村一带的大理石进行开发,从而实现该乡经济的强劲增长。(三)建设规模、生产方法及产品方案1、建设规模本项目建设规模为年开采加工大理石300平方米。2、生产方法本项目采取露天开采矿石,然后进行深加工。3、产品方案本项目产品为大理石,主要用于建筑装饰,年开采加工大理石300平方米。(四)主要建设条件1、原材料供应在婺源县古坦乡水岚村建设采石场,供应本项目原材料。2、电力供应目前
3、,该区域有高压线路,由供电部门进行增容,即可满足生产所需。3、供水本项目所在地有高山自来水,可提供本项目生产所需。4、场址建设条件(1)地理位置:矿区位于江西省婺源县古坦乡水岚村南面2公里的白石山,行政上属古坦乡管辖,地理座标:东经11738141173901,北纬293027293053,面积约1平方公里。(2)地形状况:矿区内为低山丘陵地貌,山脊呈北东南西走向,海拔最高点533米,最低点330米,相对高差约200米左右,矿区外围东南侧地势较高,最高峰桶来尖933米。(3)交通:矿区距婺源县城北面约70公里,西邻景德镇市浮梁县,水岚村距国家森林公园的xx洞府有5公里,有乡级公路相通。5、气候
4、条件矿区属中亚热带东南季风气候,温暖湿润,年平均气温16.7,其中一月份平均气温4.5,七月份平均气温28,年平均降水量为1821毫米,年平均无霜期251天,全年日照时数1868.4小时。二、市场预测面对21世纪的城市化和集镇化建设,对市政建设的要求越来越高,建筑材料的需求也越来越大,特别是大理石等高档建筑材料更是具有广泛的用途,尤其是我县,至今尚无一个大理石厂,所有的建筑材料都从外省市购进,每年需求量很大。因此,对该乡大理石矿的开采,将有广阔的市场前景,也必将带来可观的经济效益。三、建设条件(一)自然条件1、矿区构造矿区处于景德镇祁门断裂带的南东部,主要构造形态表现为二条北东向区域断裂斜贯矿
5、区,使前震旦系地层与上古生化碳系地层呈断层接触。矿区内F1,正断层,位于矿体的北西部,平均走向北东20,断层面倾向北西,倾角较陡而近于直立,该断层在矿区I线至O线间切割大理岩矿体,断层南东盘为大理岩,而北西盘仅见极少量的含大理岩化的微晶灰岩。受断裂构造的影响,矿体中的节理裂隙较发育,主要表现为剪节理,共有四组,其产状为20248586,1982017489,2702947377,11054,以20248586的这组节理较发育。矿区褶皱形态简单,为一走向北东的单斜构造,由于矿区位于水岚石城短轴向斜盆地的北东端,矿区地层由北向南,走向由北东10逐渐转变为北西340,而地层倾角一般在1521之间。2
6、、岩浆岩矿区北东部有较大的燕山早期花岗岩出露,呈岩基状产出,为中细粒二云母花岗岩。矿区内出露二处中细粒花岗岩,以岩枝状侵入于石灰系地层中,与花岗岩接触的微晶灰岩均已大理岩化,或含大理岩化,未见其它蚀变特征。3、矿体形态、产状及特征矿体赋存于石炭系上统船山组中段(C3C1-2)地层中,呈单斜层状产出,总体产状为26018,矿体北西端产状呈弧型往南西236偏转。矿体出露长约600米,宽约300米,矿体沿倾向延深大于80米,平均厚度约25米左右,矿体位于当地侵蚀基准以上。出露最高点海拔标高约470米左右,最低点约390米左右。矿体沿走向上质量变化稳定,沿倾角偶见少量未完全大理石化的微晶灰岩,矿体由北
7、向南大理石重结晶程度逐渐增高,其结晶粒度也逐渐增大。大理岩层厚一般为12米,局部层厚为50左右。矿体内节理较发育,节理密度:沿走向为1.5条/米,沿倾角为1条/米,矿区岩溶较发育,岩溶形态主要为溶沟石芽及小型溶斗。4、矿石品种矿体内矿石品种单一为白色大理石,赋存于石炭系上统中段(C3C1-2)地层中,呈白色至乳白色,细粒结构,块状结构,磨光后,为强油脂光泽,质地细腻,洁白如玉,类似“汉白玉”。镜下岩石主要有方解后组成,含量高达99%,另有少量褐铁矿,含量约占1%,方解石主要为等轴粒状和多边形晶体,大小在0.10.25,在重结晶的方解石周围不均匀分布着约占10%未重结晶的微粒状方解石。(二)开采
8、技术条件由于矿体裸露于地表,且位于侵蚀基准面以上,未来矿山开拓方式应为山坡露天开采。矿体及矿体顶底板岩性稳定,产状平缓,不易产生层间滑动,故开采技术条件简单,但由于矿区岩溶较发育,加之岩石节理的发展,所以在开采中应注意矿体的崩落与塌陷,以保证矿山开采安全。(三)矿区规模1、古坦水岚大理石矿赋存于石炭系上统船山组中段地层中,呈单斜层状产出,倾向偏西,倾角较缓,矿体位于当地侵蚀面以上,出露长600米,宽300米。2、矿石类型单一为大理岩,类似“汉白玉”,其质量沿走向倾向变化稳定,是一种观赏和经济价值较高的饰面材料。3、矿区节理较发育,节理密度走向为1.5条/米,沿倾向为1条/米,矿体荒料率为33.
9、68%,总荒料体积为20.72万立方米,剥采比为3:1。4、根据一般荒料储量利用率70%计算,矿山服务年限按12年计算,本矿区年产荒料为1.73万立方米,故该矿为中大型上乘大理石矿山。四、环境保护(一)设计中采用的环境质量标准1、工业企业厂界噪声标准(GB12348-90)2、污水综合排放标准(GB8978-96)(二)项目主要污染1、大理石加工过程中有含无机物的废水。2、大理石加工过程中会产生噪声。(三)治理方法1、含无机物的废水因废水中的污染物主要是悬浮的泥沙粉尘等无机物,其废水排入水体,会增加水的浊度,改变水的颜色,其悬浮固体沉积沙底,淤塞沙道,危害水体底栖生物的繁殖,影响渔业生产;用于
10、灌溉农田,会堵塞土壤气化,影响通风,不利于作物生长。因此,废水一定要经过处理后,达到允许标准方可排放。因处理这些废水不用改变其物质的化学性质,可采用物理方法,一般常用沉淀(重力分离)法进行处理,最简单的办法是设置沉淀池,待悬浮物沉淀后,溢流出来的清水一般可循环使用。大理石板材制作要消耗大量的水,每制作1m2板材约消耗2.5t左右水,而消耗总水量中,粗磨、细磨加工耗水量占80%左右。水在板材的磨制加工时,不仅对磨具和板材起冷却作用,而且能将磨削下来的泥粉冲走,以便继续进行生产。这些废水含大量的悬浮物,一般高达500/L以上,排出废水呈碱性,如不处理,直接排放,既浪费水资源又对环境造成污染。处理方
11、法可采用沉降池自然沉降或者投放混凝剂进行混凝沉降(如投放硫酸铅、聚合氯化铝、三氯化铁、硫酸亚铁、聚丙烯酰胺等),澄清后的水可循环使用。建议本项目采用两级机械脱水对污水进行处理,第一级用NZ型浓缩机对废水进行浓缩,水中98%左右的悬浮物在浓缩机中自然沉淀,由浓缩机排出的水再进入投放有混凝剂的加速沉清池中进行二次处理。经处理后的水中含悬浮物降至1570/L,水质稳定,可循环使用。第二级处理是把浓缩后的污泥进行脱水,使其变为固态(泥饼),泥饼可作填料制作钙塑制品,也可代替白灰膏拌制砂浆等。详见下图。2、噪声因在打磨大理石时会产生噪声,建议采用吸声、隔声,对工人个人保护等措施进行噪声治理。(1)吸声:
12、用吸声材料或吸声结构建设厂房。(2)隔声:在噪声较大的车间,采取隔声较好的材料,使其噪声降低。(3)个人防护:采取限制工作时间和戴防护装置,工人使用耳塞、防声棉(蜡浸棉花)、耳罩、帽盔等。3、矿石开采后,矿区会产生裸露的土壤,建议在矿石开采后,采取绿化和植树的方法,防止水土流失。五、职业安全与工业卫生(一)采用的设计规范和标准1、中华人民共和国劳动令第3号建设项目(工程)劳动安全卫生监察规定(1997年1月1日施行)。2、工业企业设计卫生标准(TJ36-79)。3、工业企业噪声控制设计规范(GBJ87-85)(二)工业卫生措施1、防尘项目设计中贯彻预防为主的方针,工艺布置上尽量减少不必要的环节
13、,减少物料运转点数目和物料差。2、防噪声在工艺设计方面尽量选用低噪声设备,同时进行个人防护,使工人在噪声强度小于70db(A)的环境下进行工作。(三)劳动安全措施1、在机械设备处理置防护罩,设置电气控制开关。2、在矿区内危险地段设置警告牌。3、对振动较大的设备采用减振措施,降低噪声。4、对上岗操作人员进行安全教育,合格后方可上岗。六、企业组织及劳动定员(一)企业组织建议本项目采用厂长负责制,由负责生产和销售的两位副总经理负责日常工作,下设办公室、质检、财务等部门。(二)劳动定员本项目生产项目二班制运转,具体定员根据本项目的实际进行定员,全年工作时日为300天。七、投资估算及经济效益分析(一)投
14、资估算本项目总投资估算为732.34万元。投资构成及分布如下:1、建筑工程费估算为25万元,其中:厂房12万元,材料仓库5万元,其它用途房屋8万元。2、设备及工器具购置费30万元,其中:开采机4台28万元/台=112万元;切割机4台6万元/台=24万元;水磨机4台4万元/台=16万元;刨光机2台26万元/台=52万元;吊车2辆28万元/辆=56万元;运输车3辆16万元/辆=48万元。待添加的隐藏文字内容23、安装工程费估算为57.2万元。4、其它费用估算为122.14万元(包括管理费、勘察设计费、设施费、配套费、生产准备费等)。5、预备费估算为60万元。6、铺底流动资金估算为160万元。(二)
15、经济效益分析本项目日开采加工大理石300m2,平均售价为50元/m2,年可开采加工大理石9万平方米,年销售收入可达450万元。本项目总生产成本估算为180万元,销售成本为20万元,年利润总额可达250万元,扣除税收,税后利润可达173.5万元。产品经济效益核算表明:建筑装饰材料以50元/m2计,年销售收入可达450万元,剔除生产成本和销售成本及上交国家税收可获纯利润173.5万元,预计4.3年可收回全部投资,具有非常明显的经济效益,是一个比较理想的投资项目。Editors note: Judson Jones is a meteorologist, journalist and photogr
16、apher. He has freelanced with CNN for four years, covering severe weather from tornadoes to typhoons. Follow him on Twitter: jnjonesjr (CNN) - I will always wonder what it was like to huddle around a shortwave radio and through the crackling static from space hear the faint beeps of the worlds first
17、 satellite - Sputnik. I also missed watching Neil Armstrong step foot on the moon and the first space shuttle take off for the stars. Those events were way before my time.As a kid, I was fascinated with what goes on in the sky, and when NASA pulled the plug on the shuttle program I was heartbroken.
18、Yet the privatized space race has renewed my childhood dreams to reach for the stars.As a meteorologist, Ive still seen many important weather and space events, but right now, if you were sitting next to me, youd hear my foot tapping rapidly under my desk. Im anxious for the next one: a space capsul

20、esday, I sat at work glued to the live stream of the Red Bull Stratos Mission. I watched the balloons positioned at different altitudes in the sky to test the winds, knowing that if they would just line up in a vertical straight line we would be go for launch.I feel this mission was created for me b
21、ecause I am also a journalist and a photographer, but above all I live for taking a leap of faith - the feeling of pushing the envelope into uncharted territory.The guy who is going to do this, Felix Baumgartner, must have that same feeling, at a level I will never reach. However, it did not stop me
22、 from feeling his pain when a gust of swirling wind kicked up and twisted the partially filled balloon that would take him to the upper end of our atmosphere. As soon as the 40-acre balloon, with skin no thicker than a dry cleaning bag, scraped the ground I knew it was over.How claustrophobia almost
23、 grounded supersonic skydiverWith each twist, you could see the wrinkles of disappointment on the face of the current record holder and capcom (capsule communications), Col. Joe Kittinger. He hung his head low in mission control as he told Baumgartner the disappointing news: Mission aborted.The supe
24、rsonic descent could happen as early as Sunday.The weather plays an important role in this mission. Starting at the ground, conditions have to be very calm - winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lo
25、wer level of the atmosphere (the troposphere) where our day-to-day weather lives. It will climb higher than the tip of Mount Everest (5.5 miles/8.85 kilometers), drifting even higher than the cruising altitude of commercial airliners (5.6 miles/9.17 kilometers) and into the stratosphere. As he cross
26、es the boundary layer (called the tropopause), he can expect a lot of turbulence.The balloon will slowly drift to the edge of space at 120,000 feet (22.7 miles/36.53 kilometers). Here, Fearless Felix will unclip. He will roll back the door.Then, I would assume, he will slowly step out onto something
27、 resembling an Olympic diving platform.Below, the Earth becomes the concrete bottom of a swimming pool that he wants to land on, but not too hard. Still, hell be traveling fast, so despite the distance, it will not be like diving into the deep end of a pool. It will be like he is diving into the sha
28、llow end.Skydiver preps for the big jumpWhen he jumps, he is expected to reach the speed of sound - 690 mph (1,110 kph) - in less than 40 seconds. Like hitting the top of the water, he will begin to slow as he approaches the more dense air closer to Earth. But this will not be enough to stop him com
29、pletely.If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down. His team hopes its not needed. Instead, he plans to deploy his 270-square-foot (25-square-meter) main chute at an altitude of around 5,000 feet (1,524 meters).In order to depl
30、oy this chute successfully, he will have to slow to 172 mph (277 kph). He will have a reserve parachute that will open automatically if he loses consciousness at mach speeds.Even if everything goes as planned, it wont. Baumgartner still will free fall at a speed that would cause you and me to pass o
31、ut, and no parachute is guaranteed to work higher than 25,000 feet (7,620 meters).It might not be the moon, but Kittinger free fell from 102,800 feet in 1960 - at the dawn of an infamous space race that captured the hearts of many. Baumgartner will attempt to break that record, a feat that boggles the mind. This is one of those monumental moments I will always remember, because there is no way Id miss this.
