Reddit mentions of Operations Management For Competitive Advantage

It really depends on what your goal is for the reference and if you have any further education or learning goals beyond it.

The Management of Mineral Resources book will help you understand the decisions of you company executives and provide decent insight into what decisions may be coming next depending on the economic and financial environment, but is weakened in its overall usefulness in that all the problems given and solved are already all pre-scoped, and that some of the advice and direction can be ludicrously wrong from operation to operation. On top of that the information aggregation and decision making process is all about 3-4 levels above the actual operations, and so will be completely different to anything you are likely seeing currently or in the near-to-mid future.

The Mine Manager's Handbook is useful to understand the Mine Manager's decision and process (the obvious answer, I know), but I suspect from looking through the contents pages it is mainly about dealing with constraint and polling responsible parties while providing direction rather than identifying, solving, and optimising approaches to issues.

A more general reference like Operations Management for Competitive Advantage is so general that you will often wonder how you could apply it to your current circumstance (and examples in books like that are almost exclusively manufacturing or supply-chain related), but gives you the insight into the driving factors of decisions from the bottom-up. This is the book if you want to understand how the blast crew, mining maintenance planning, mineral process group, grade control, et al. manage to actually create a final product in a reasonable time, cost, and continuously. So it is a book about the individual steps to The Dance that is the many hundreds of daily interactions and compromises that make an operation function, while the Mine Manager's Handbook is about choreography and managing the dancers, and the Management of Mineral Resources is about producing and selling the music video the dance is in. Hopefully that analogy isn't too forced or ridiculous.

On a personal front, I tend to dislike the first kind of book as it is designed around MBAs coming in without a great understanding of the industries that are being written about (so, for people focused on business, rather than people who focused on an industry then wanted the business knowledge). The second kind of book is a useful reference on the various groups that need to be managed, but (likely) focuses on directing, managing, and integrating their output rather than understanding or producing the outputs, and often times most of the information that the book contains could be easily had at any time with a simple question at work (and if the question are discourage then you have a useful bit of info about your corporation and your value in it). And the last kind of book is a good learning resource, and useful to the times in your career where you may be in other industries, but requires a lot of personal thought on "where the hell does this apply in what I am looking at?"

Operations Management is pretty neat and useful stuff to go into and study and is one of those fields where so many people think they know what is going on (because they have studied Project Management) but are usually unaware of the real driving factors and directions.
