To study the strength and permeability characteristics of cemented tailings backfill with different cement–sand ratios waste rock contents, uniaxial compression test were carried out respectively. The porosity backfills after solidification was observed by scanning electron microscope. effects ratio content on internal overall studied. results showed that have certain body. When fixed, compressive body increased first then decreased increase content. 10%, reached maximum, when 30%, maximum....
Tailing cement filling is an important development direction in mine filling, as it a green and environmentally friendly method for efficiently treating solid waste mines. Adding certain amount of rock can effectively improve the backfill strength better meet requirements. To address use tailings cemented materials, uniaxial compression test was carried out on backfills with different cement/sand ratios contents, influence ratio content studied. This study found that when certain, increases...
A polarization reconflgurable spiral slot antenna with states switched among left-hand circular (LHCP), right-hand (RHCP) and linear polariza- tion (LP) is proposed in this paper. The consists of a copla- nar waveguide (CPW) input, pair CPW-to-slotline transitions, two separated same size single-arm radiators, four PIN diodes for reconflgurability. good impedance match (VSWR 6 2) both achieved from 2.1 to 2.9GHz. bandwidth axial ratio AR 3dB RHCP LHCP ranges 2.27 2.66GHz (15%). simulation...
In order to establish storages in mining goaf, calcium bentonite (Ca-B), slag powder (SP) and silica fume (SF) were added into the backfill obtain a cemented with high stability certain anti-seepage function. Uniaxial compressive strength (UCS), porosity, permeability scanning electron microscopy (SEM) tests carried out. Results show that SP SF can significantly improve at same level of incorporation, highest increases are 229.01% 131.30% compared control group, while Ca-B has strong...
