某地一国家规划矿区内拟“上大压小”,关闭周边6个小煤矿整合新建一个大型煤矿,产煤涉及规模为400万t/a。根据项目设计文件,矿区地面有设计主井和副井各一处,通风井两处,洗煤厂一处。洗煤厂设尾矿库一座,洗煤废水能够重复利用。工程设矿井水地面处理站一个,拟配套建设一个瓦斯抽放站用于发电,并建设矸石场储存矸石作建筑材料。矸石场选在开采境界边缘地带的一处山凹内,预计可堆放矸石30年。该矿区雨量充沛,植被丰富,易发生泥石流,区内农作物种类繁多。井区范围内有泉点1 5个,其中5个为村民饮用水源。开采境界内有中型河流一条,为下游某城市的饮用水源。工程预测最大沉陷区内有村庄2个,省级文物保护单位4处,其他均为农田和林地。
问题:
1.该项目生态环境影响评价的重点内容是什么?

3.该项目环境影响评价中对沉陷区的现场调查主要包括哪些内容?
4.从目前国家煤炭产业政策要求来看,本矿建成投产前必须落实哪些措施?
5.该项目中,煤矸石堆场大气污染物控制因子是什么?

People need to be active to be healthy. Our modem lifestyle and all the conveniences we’ve become used to have made us sitting much of the time - and that’s dangerous for our health. Sitting around in front of the TV or the computer, riding in the car for even a short trip to the store and using elevators instead of stairs, all contribute to our inactivity. Physical inactivity is as dangerous to our health as smoking!
Add up your activities during the day in periods of at least 10 minutes each. Start slowly ... and build up. If you’re already doing some light activities move up to more moderate ones. A little is good, but more is better if you want to achieve health benefits.
Scientists say add up 60 minutes of physical activity every day to stay healthy or improve your health. Time needed depends on effort - as you progress to moderate activities, you can cut down to thirty minutes, four days a week.
