“…The bottom Quaternary layer, which is mainly composed of clay, silty clay, and marine mud, is impermeable and largely blocks contact with the pore water, seawater, and the fractured rock masses. However, this layer is variably 0.8-10 m thick and this high variability casts doubts over its impermeability (Li et al , 2014aLiu et al 2012;Zhao et al 2012a, b).…”

Seawater poses a great threat to the Xinli Mine, an undersea gold mine in China. A hydrochemical method was used to assess the risk of sea water inrush into the mine. A detailed hydrochemical survey and sampling were carried out and the concentrations of conservative ions in the mine water were analyzed. Principal component analysis indicated that the potential water inrush channels were located in the hanging wall of the ore-controlling fault. A composite principal component was calculated from the Na ? , Cl -, Mg 2? , SO 4 2-, and K ? concentrations, which reflected the effects of potash feldspathization and cation exchange, to assess the risk of seawater inrush.

“…(2) Natural sedimentation of filling slurry (Liu, Dang, & He, 2012;Zhang, Yan, & Liu, 2012). Once the area has been filled by slurry, dehydration and solidification sclerosis cause the volume of he filling material to decrease, leading to an empty top.…”

“…Gob factors in the pipeline filling of top pick present many challenges, and numerous measures have been developed to overcome these. But each of these measures only applies under certain circumstances and tackles particular factors: gob is a world filled with top pick technical problems (Liu, Dang, & He, 2012). Thus in the implementation of top pick filling operators must adopt a variety of measures to achieve the best results.…”

“…(1) Partition filling (Liu, Dang, & He, 2012): when filling a stope with a large area, in order to minimize the empty area that fills with the slurry produced by the impact of natural slope angle docking at the top rate, it is necessary to fill the empty area to partition the top pick. The key to success in this process is the size of the top pick partition rather than quality.…”

<p class="1Body">Due to the increasing depth of mines, fill mining is increasingly widely used in metal mines. As a result, supporting pit roofs has become an important issue to which an increasing number of people are devoting attention. This paper analyses the factors affecting the rate of supporting pit roofs under stope filling conditions, including filling slurry properties and the filling process. Building on this, the paper examines a number of potential measures for improving the rate of supporting pit roofs, including creating good conditions for filling, optimizing filling slurry properties, eliminating the problems caused by water and improving filling technology. Mining companies must select from these measures according to the particular conditions in which their mines operate, but given the right conditions all of the measures examined have the potential to increase the rate at which pit roofs are supported.</p>
