🔥 آتشکاری در معدن Chinchillas

معدن Chinchillas یک معدن روباز نقره-سرب-روی (Ag-Pb-Zn) واقع در استان Jujuy در شمال آرژانتین است. این معدن توسط شرکت SSR Mining Inc. اداره می‌شود و به‌عنوان منبع خوراک (Ore Feed) برای کارخانه فرآوری معدن Pirquitas عمل می‌کند.

⚙️ روش‌های به‌کاررفته در آتشکاری معدن Chinchillas:

🔹 نوع معدن: روباز (Open-Pit)

🔹 نوع چال (Blast Hole Type): چال‌های عمودی و گاهی زاویه‌دار بسته به هندسه پله‌ها

🔹 قطر چال‌ها (Hole Diameter): 165-200 mm (رایج در معادن متوسط فلزی)

🔹 نوع خرج انفجاری (Explosive Type):
- عمدتاً Emulsion Explosives → به دلیل پایداری بالا، حساسیت کنترل‌شده و قدرت یکنواخت
- در برخی مقاطع از ANFO در ترکیب با امولسیون استفاده می‌شود (برای کاهش هزینه)

🔹 الگوی چال‌گذاری (Blast Pattern):
- متغیر، بسته به سنگ‌شناسی و مقاومت سنگ → اغلب rectangular یا staggered pattern
- فواصل چال (Burden / Spacing) بهینه‌شده با مدل‌سازی لرزش و خردایش

🔹 سیستم آتشکاری (Initiation System):
عمدتاً از Electronic Detonators (EDs) استفاده می‌شود
✅ مزایا:
- دقت بالای زمان‌بندی (Millisecond Precision)
- کاهش پراکندگی نتایج خردایش
- مدیریت بهتر انرژی و لرزش

"طراحی هوشمندانه آتشکاری در معدن Chinchillas به شرکت SSR Mining کمک کرده است تا با افزایش بهره‌وری، بهبود ایمنی و رعایت الزامات محیط‌زیستی، عملیات معدنکاری خود را در این پروژه بهینه کند."

How to Invest in Bitcoin?

Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
