What are the recent new stories about acid mine drainage?
There may be stories regarding new regulations on acid mine drainage in certain regions. This could involve stricter limits on the amount of pollutants that can be released from mines, which is a significant development as it helps protect the environment. Mines would then have to invest in better treatment and prevention methods to comply with these regulations.
Can you share some new stories about acid mine drainage?
Sure. A new story might be about a mine that has successfully implemented a new technology to reduce acid mine drainage. This technology could be a cost - effective solution that other mines can also adopt.
What are the recent top stories involving lysergic acid diethylamide?
A recent top story could be about new research findings on LSD's long - term effects on the brain. Scientists are trying to understand if there are any permanent changes in the neural pathways. Another might be about the underground market for LSD and how law enforcement agencies are trying to combat it. There are also stories about the increasing awareness in the medical community about the potential of LSD in mental health treatment.
Open ditch drainage, underground ditch drainage
Open ditch drainage and underground ditch drainage were two different drainage methods. Open ditch drainage referred to the digging of open ditches on the surface to guide water to the water outlet. It was suitable for draining accumulated water after heavy rain or for green areas with uneven terrain. Open ditches had the advantage of easy drainage, easy flushing, and anti-blockage, but there might be problems with odors and pests, and it would also make the ground uneven. Underground ditch drainage was used to draw water out by burying pipes or building underground ditches. It was suitable for narrow sites and large underground water. Underground ditches could keep the terrain neat and save land, but the cost was higher. There were differences in drainage methods, cover materials, and functions between open ditches and underground ditches.
Open ditch drainage and underground pipe drainage
Open ditch drainage and underground pipe drainage were two common methods of farmland drainage. Open ditch drainage was a method of digging drainage ditches to form a drainage ditch network. Water would flow from the field ditch network into the water transmission ditch network and finally into the drainage area (river, lake, sea). Underground drainage was a method of burying pipes underground to drain water by removing excess water from the farmland soil and lowering the water level. The underground pipe drainage could be used to filter and seep water by using sand and stone bedding, laying thick plastic pipes and crushed sand. Open ditch drainage was suitable for soil layers with better geological conditions, while underground pipe drainage could effectively control the underground water level, save land, and have a better drainage effect.
Open ditch drainage and underground ditch drainage
Open ditch drainage and underground ditch drainage were two different drainage methods. Open ditch drainage referred to the drainage of water through the excavated open ditch channel. Water could flow directly from various positions in the ditch. The cover was usually a comb, which could pass water. The comb or grill was used to intercept debris. Underground ditch drainage meant that water could not flow in directly. The cover was usually steel plate or concrete. The drainage ditch of the underground ditch was inclined to the water collecting well. When digging, the drainage ditch was first dug, and as it was dug, it deepened to form a underground ditch system connecting the inside and outside of the foundation pit to control the underground water level. Finally, the underground water was pumped away by a pump. Open ditch drainage was suitable for irrigation in areas with water infiltration, and it had a good effect on rainwater drainage. Dark ditch drainage was suitable for the foundation pit drainage of structures with large foundation pit depth, narrow site, and strong underground water.
