此外，国际市场的变化也会对煤炭价格产生影响。例如，国际政治局势的紧张、主要煤炭生产国的生产状况等，都可能引发煤炭价格的波动。

综上所述，每年煤炭的涨价时间并非固定不变，而是受到多种因素的影响。投资者和消费者需要密切关注市场动态和政策变化，以制定合理的投资和消费策略。

Coal, as an important energy resource, plays a pivotal role in the global energy market. Its price is influenced by various factors, including supply and demand, seasonal demand, and policy adjustments. So, when does coal prices rise each year?

Firstly, it is essential to understand that coal price fluctuations exhibit certain seasonal patterns. Typically, before the winter season, coal prices tend to rise. This is because winter is the peak demand period for coal, and countries increase their coal procurement to ensure energy supply, thereby pushing up coal prices.

Secondly, coal prices are also affected by policy adjustments. Governments may introduce relevant policies to balance the energy market, protect the environment, or adjust the industrial structure, which often lead to fluctuations in coal prices.

In addition, changes in the international market can also impact coal prices. For instance, international political tensions, production conditions in major coal-producing countries, and other factors can trigger fluctuations in coal prices.

In conclusion, the timing of coal price increases each year is not fixed but influenced by various factors. Investors and consumers need to closely monitor market dynamics and policy changes to formulate reasonable investment and consumption strategies.
