 — In mining, deposits are divided into blocks, forming the basis for open-pit mine planning, covering production and haulage route planning. Current studies often stage optimization and lack the consideration of road capacity, leading to suboptimal solutions. A novel approach integrates production scheduling and haulage route planning through a …

 — A proposed ban on open pit mining in Mexico will create risks to miners even after President Andrés Manuel López Obrador's term ends in September, analysts and miners said.

 — A committee in Mexico's lower house of Congress passed two constitutional reforms on Wednesday that would prohibit open-pit mining and fracking.

 — The Mining Reform imposes tighter regulations on the mining industry through amendments to the Mining Law, the National Water Law, the General Law for Ecological Balance and Environmental …

 — Tested on a real open-pit coal mine with over 5 million blocks, this approach reduces haulage costs by 10.06% compared to stage optimization. Additionally, this approach allows for adjusting haulage …

 — The apparent ban on open pit mines contrasts with the nationalization of lithium mining in Mexico early last year. Hard rock lithium mining is usually best suited for open pit, bulk mining methods.

 — A mining complex is a value chain with multiple components: deposits, stockpiles, processing destinations and transportation systems. Optimizing a mining complex demands the simultaneous optimization of all its components, a problem known in the mining literature as global optimization of mining (Whittle 2007, 2018).Several …

 — Globally, coal continues to be a vital resource for energy production as well as manufacturing and construction. In 2013, coal provided 30.1% of global primary energy needs and generates over 40% of the world's electricity and also was used in the production of over 70% of the world's steel (World Coal Association 2014a).A review of the …

 — Particulate matter (PM) is one of the main actors related to air pollution caused by surface mining. Fugitive dust, considered as particulate matter that cannot be collected by conventional measures, is classified by the particle size. The Environmental Protection Agency (EPA) categorizes PM as coarse and fine particles based on the …
