随着回采工作面的推进,逐步用充填料充填采空区的采矿方法叫充填采矿法,有时还用支架与充填料相配合,以维护采空区。充填采空区的目的,主要是利用所形成的充填体进行地压管理,以控制围岩崩落和地表下沉,并为回采创造安全和便利的条件。充填采矿法也有多种,下列关于这些方法的说法中不正确的是()。

A. 单层充填采矿法。此法适用于缓倾斜薄矿体,在矿块倾斜全长的壁式回采面沿走向方向、一次按矿体全厚回采,随工作面的推进、有计划地用水力或胶结充填采空区,以防顶板崩落
B. 上向水平分层充填采矿法。此法一般将矿块划分为矿房和矿柱,第一步回采矿,第二步回采矿房。回采矿房时,自下向上水平分层进行,随着工作面向上推进,逐层充填采空区,并留出继续上采的工作空间。充填体围护两帮围岩,并作为上采的工作平台。崩落的矿石落在充填体的表面上,用机械方法将矿石运至留井中。矿房采到最上面分层时,进行接顶充填
C. 上向倾斜分层充填采矿法。这种方法与上向水平分层充填法的区别是,用倾斜分层回采,在采场内矿石和充填料的搬动主要靠重力
D. 下向分层充填采矿法。这种方法适用于开采矿石很不稳固或矿石和围岩均很不稳固,矿石品位很高或价值很高的有色金属或稀有金属矿体。这种采矿方法的实质是从上往下分层回采和逐层充填,各分层的回采由上一层假顶保护

听力原文:W: Good afternoon. ABC Apartments. May I help you?
M: Yes, I'm interested in renting a one-bedroom apartment. Do you have any available?
W: No, I'm sorry. None are available at this time, but I expect a vacancy in about three weeks. Could I interest you in a two-bedroom?
M: Well, I'm a student and I have to cut corners. How much more would a two-bedroom apartment cost me?
W: This one-bedroom rents for $150 a month and the two-bedroom is only 35 dollars more.
M: Is the two bedroom a great larger than the one-bedroom?
W: Yes, it is. Also, I might tell you that the one-bedroom doesn't have a dishwasher. All of our two-bedroom apartments do.
M: What about signing a lease?
W: We do require a 6-month lease, and there is a deposit of $100 in case any damage is done to the apartment.
M: When could I see an apartment?
W: How about later this afternoon? Let's see. I have an appointment at half past three and another at four. How about five o'clock this afternoon?
M: That would be fine. I'll pick my wife up from work and we'll come right over.
W: I'll be looking forward to seeing you then.
M: Thank you. Good bye.
